It also seems to do the escaping for you as it handled text containing commas

Re: Stuck on native database functions

[Terence Heaford via use-livecode]

Mark, it certainly helps me.

The routine I have working is

put "uniqueID,date,type,description,amount,balance,category" into tFields

put merge("INSERT INTO [[tAccountName]] ([[tFields]]) 
VALUES(:1,:2,:3,:4,:5,:6,:7)") into tSQL

revExecuteSQL dbGetID(), tSQL, "tValues[uniqueID]", "tValues[date]", 
"tValues[type]", "tValues[description]", "tValues[amount]", 
"tValues[balance]","tValues[category]"

put the result into tErr

return tErr


It resolves the error I was getting relating to autoincrement.

Thanks

Terry

Re: Stuck on native database functions

[Terence Heaford via use-livecode]

Out of interest and not sure if it is relevant but I have received this error:

"table myTable has 8 columns but 7 values were supplied"

Yes the table has 8 columns in total but the first column is

recID integer primary key autoincrement

Surely it should not give this error because I do not provide the value as this 
is autoincrement

All the best

Just tried this method

revExecuteSQL myID, "insert into mytable values(:1,:2,:1)", "valueX",”valueY"

It did not work

put 
merge("[[quote]][[tUniqueID]][[quote]],[[quote]][[tDate]][[quote]],[[quote]][[tType]][[quote]],[[quote]][[tDescription]][[quote]],[[quote]][[tAmount]][[quote]],[[quote]][[tBalance]][[quote]],[[quote]][[tCategory]][[quote]]")into
 tValues

put ":1,:2,:3,:4,:5,:6,:7" into tPlaceHolders

put merge("INSERT INTO [[tAccountName]] VALUES([[tPlaceHolders]])") into tSQL

put tSQL & " " & tValues

revExecuteSQL dbGetID(),tSQL,tValues


Not sure what to try next

Re: Stuck on native database functions

I have now tried your method with the tValues array directly and by 
deconstructing the array as below and it does not work. I have a recollection 
of not being able to get this to work with an array which is why I did the way 
I did.


All the best

put q(tAccountName) into tAccountName

put q(tValues["uniqueID"]) into tUniqueID

put q(tValues["date"]) into tDate

function dbAddTransaction tAccountName,tValues

put q(tAccountName) into tAccountName

put q(tValues["uniqueID"]) into tUniqueID

put q(tValues["date"]) into tDate

put q(tValues["type"]) into tType

put q(tValues["balance"]) into tBalance

put q(tValues["category"]) into tCategory

put "uniqueID,date,type,description,amount,balance,category" into tFields

put 
merge("[[tUniqueID]],[[tDate]],[[tType]],[[tDescription]],[[tAmount]],[[tBalance]],[[tCategory]]")into
 tValues

put merge("INSERT INTO [[tAccountName]] ([[tFields]]) VALUES([[tValues]])") 
into tSQL

revExecuteSQL dbGetID(), tSQL

put the result into tErr

return tErr

end dbAddTransaction

Re: LiveCode convert seconds to dateItems - year is out by 19?

[Terence Heaford via use-livecode]

Could it be something to do with the base date on the mac vs the base date of 
live code?

I believe the base date on a mac is 1970, not sure what it is in live code?

Re: Polygons

[Terence Heaford via use-livecode]

I also have concluded this.

If you miss out lines the opaque setting is irrelevant, it functions as being 
false.

Is this a bug?

My work around is two polygons one underneath (filled) and the other on top 
(with lines)

You could just draw lines between the points that need them, using a polygon as 
a line. I have tried this and it does not impact performance.

Thanks for all your help

Re: Polygons

[Terence Heaford via use-livecode]

OK, I have changed your script by adding these lines to the mouseUp handler

set the backgroundColor of grc "myPoly" to red

set the forecolor of grc "myPoly" to blue


Now if you switch the lines on/off you will see that the fill does not work 
without all lines.

Not sure what this means exactly.

Re: Polygons

[Terence Heaford via use-livecode]

Thanks for your example.

I am basic filling underneath a line chart to make an area chart but the 
closing lines to the x-Axis do not have a line.

I concluded to draw a polygon twice once with fill and no lines, filled to the 
x-Axis and overlay it with a similar polygon but not starting/finishing at the 
x-Axis but finishing at the first/last point. (hope this makes sense).

Will play with your example.

Thanks

Terry

Re: Polygons

[Terence Heaford via use-livecode]

When you do this it appears to affect the fill settings. I lose the fill where 
there are no lines and the closure of the points also moves.

I can’t believe it’s LC, it must be me. A simple script example would be useful 
if you have the time.

A square, that’s easy, that has the side lines missing and is filled with a 
colour.

Re: Polygons

[Terence Heaford via use-livecode]

Thanks for that, clearly understood.

To expand on the original question. If you have a hexagon, is it possible  to 
only draw lines on sides 1,3,5,6 and no lines on sides 2,4.

Thanks Terry

Copy Script vs Behaviours

[Terence Heaford via use-livecode]

I have a card with a group which is to hold the objects when I create a chart.

I have pie, bar and line chart substack libraries for each with the code 
contained in the stack script.

When the user changes the type of chart I have been using:

set the script of myGroup to the script of stack myChartLib and to be fair this 
works well.

I have not used behaviours before and have just switched to that method by 
changing the behaviour of the chart object to the substack script and that also 
seems to work, although without doing a test I can’t be sure but changing the 
script does seem a little quicker.

Can anyone provide some insight into any benefit of using one way over the 
other.


Thanks

Browser Widget

[Terence Heaford via use-livecode]

I believe the Browser Widget uses the native browser and in that case it uses 
the same code as Safari on MacOS?

I have been using CanvasJS to create some charts and have been rendering the 
result in the Browser Widget using Set the URL of …..

These charts have been created on the computer and not via the internet.

Generally they render well except for the animation of the chart.

In Safari it's as smooth as silk.

In the Browser Widget there is some slight stutter that does slightly affect 
the user experience.

Does anyone know why this stutter exists with the Browser Widget and not with 
Safari and is there a solution?


Thanks

Terry

Re: lock screen

Thanks for all the replies.

How does lock screen affect widgets?

It does not appear to have any effect as if you run a Javascript in a Browser 
having applied lock screen, the Browser widget seems unaffected.

lock screen

[Terence Heaford via use-livecode]

Just looking for clarity with regard to lock screen.

Is there only one state for the screen, either locked or not locked and when is 
that state changed.

---
on mouseUp

lock screen

aTest

end mouseUp


on aTest

— is the screen still locked here

end aTest



At what point is unlock screen called by livecode without me calling it 
directly.

The docs say when all pending handlers have completed but what exactly is a 
pending handler.

Re: Building a Standalone MacOS App in 9.6.1

[Terence Heaford via use-livecode]

Hi Panos,

That’s just a typo correction by MacOS mail. I actually applied the sudo call 
as you suggested.

I have not replied because as a trial I have now done a full install of Xcode 
12.3 from the App Store which as usual asked me to install the additional 
components. I did this.

Now when I build a standalone with LC it works.

Whatever was missing seems to have been corrected by the Xcode install.

I will not be removing Xcode now but it gives me an excuse to play with SwiftUI 
to see how it performs.

Thanks to everyone for their suggestions.


Terry

Building a Standalone MacOS App in 9.6.1

[Terence Heaford via use-livecode]

I thought I would try to build a standalone app with the Community Edition in 
Catalina 

Many errors. Perhaps someone could shed some light.

This error is the first. "replacing existing signature xcrun: error active 
developer path”

I did see a comment on the LC Forum that suggested

sudo xcode-select —install, to install the command line tools.

I carried this out, still no luck.

Installed 9.6.1 RC1. Still no luck.

Is it necessary to have Xcode installed for this to work?


Thanks

rotatedText widget and others

[Terence Heaford via use-livecode]

Has anyone tried using this widget?

The “get the formatted height of widget” function does not appear to return the 
correct result.

Whats the point of Livecode providing a widget that does not function correctly.

It may rotate text but try aligning a number of these widgets without the 
dimensions being correct.

A complete waste of my time.

If anyone can provide details that I am missing to get this “so called” widget 
to function correctly I’ll gladly get down on my knees and apologise for this 
rant.




I’ve looked at the line chart widget, not enough functionality for a true line 
chart, rather simplistic.

Pie chart, as line chart.

End of second rant.

——

Are any of these “so called” widgets provided by LC designed to provide any 
true functionality or am I just wasting my time trying to use them.
They appear to have been knocked up during someones tea break. Not a great way 
to advertise LC’s abilities.

Printing a com.livecode.widget.browser

[Terence Heaford via use-livecode]

Clearly you can’t print a card that contains a browser widget as livecode is 
unable to do this.

I don’t understand why because Safari can and I believe they are both based on 
webkit.

Anyway I have come up with a semi acceptable workflow that involves.

1. Exporting a screenshot of the screen with the widget into a variable.

2. Pasting via script into a LC image object.

3. Then print the portion of the card containing the image.

The problem is this.

I have both the image and widget on the same card and hide the widget when I 
want to print the image and vice versa when going back to the widget.

There is a noticeable flash when hiding and showing the objects.

I am looking for ideas as to how I can minimise this flash or camouflage
it for the user.

I placed the segmented control widget in a group and put a simple

on mouseEnter
beep
end mouseEnter

in the script of the group.

This did not implement a beep sound.
I placed the same script in the segmented control and that did not make a beep 
either.


I read the dictionary for mouseEnter and it does not apply to a group, I assume 
it also does not apply to the segmented control widget.


I then created three standard buttons and placed those in a group.
Placed the above script in the group.
and each time the mouse entered a button it beeped. It did not beep upon 
entering the group.

Is all this the correct behaviour?

If it is then it is not possible to create your own tooltip for a segmented 
control widget unless there is some more fiddling that can be done.

It seems creating your own segmented control may be the only solution.

Any ideas

Thanks

Terry

Segmented Control Widget

[Terence Heaford via use-livecode]

I have been messing about with the Segmented Control Widget and have been 
trying to apply a tooltip.

I noted that the tooltip can only be applied to the whole control, it does not 
appear possible to have a tooltip for each segment.

Is this possible and if so could someone please advise.

hhOText(community.livecode.hermann.orientedtext)

[Terence Heaford via use-livecode]

I have been playing around with this community orientedText widget to see if it 
is suitable to be used for xAxis Labels at 45 degrees in a bar chart.

I’m not sure I am using it correctly.

I have set it up similar to this:

repeat for each line tLabel in tDataLabels

create widget (tLabel) as "community.livecode.hermann.orientedtext" in group 
"generalChart"

set the widgetText of widget(tLabel) to tLabel

set the widgetFontName of widget(tLabel) to "Lucida Grande"

set the widgetFontSize of widget(tLabel) to "15"

set the widgetAngle of widget(tLabel) to "-45"

set the strokeBack of widget(tLabel) to false

set the widgetAdjustSize of widget(tLabel) to true

set the right of widget(tLabel) to tX + tGap

set the top of widget(tLabel) to tY

add tGap to tX

end repeat


However, widgetAdjustSize does not adjust it’s size unless I go into the 
property dialog and uncheck/check the setting.

Can anyone help with this.


Thanks

Wrapping Text

If you have a field with one long word that is wider than the field it does not

Is there a solution to this?

Browser widget scrolling

[Terence Heaford via use-livecode]

This does not appear to work:

set the hScrollbar of widget  “myBrowser" to false

The scrollbar becomes visible when you drag resize a window.

I was expecting there to ne no scrollbar at all.

Also the checkboxes in the properties section (horizontal and vertical) do not 
work. They are always set to true.

Am I misunderstanding how this is supposed to work?

That’s the solution I was thinking about.

It’s probably necessary to capture the screen image at a larger size for

Browser

[Terence Heaford via use-livecode]

I am again looking at implementing Javascript charts within a LC browser.

Looking at amCharts.

Got a chart displaying easily within the browser widget.

Tries to print the card but the widget does not print.

So, I am left wondering if printing is impossible from within LC but then 
remembered there is another browser contained within LC.


Which should I use, the widget or revBrowser?

What is the pro’s and cons and can one print?

Re: HTML Colour Groups

[Terence Heaford via use-livecode]

It seems that LC only supports the use of names that can be found by

put the colorNames function

and

“Crimson” is not one of those.

How the names of colors included is determined, I do not know.

I just thought (clearly incorrectly) that HTML colors were included.


On another point.

When you use Hex directly as in

set the background color of graphic 1 to #FFC0CB

works but….

set tColor to “#FFC0CB”

set the background color of graphic 1 to tColor

does not.

Could someone explain how to do hex with a variable

Thanks

Terry

Re: Go to card has become slow

[Terence Heaford via use-livecode]

I have now copied the modified scripts from the project version that was slow 
and reapplied them to the previous version which was running fast.

Applying the modified scripts has not resulted in any slowdown of the version 
they have been applied to.

So, I cannot understand why the project slowed down in the first place but…

all is now well until it happens again.


Thanks

Re: Go to card has become slow

[Terence Heaford via use-livecode]

Fortunately I have Time Machine running on my mac.

I have gone back to a previous copy from the 01 April 2020 and this project is 
running at full speed.

I have made no modifications to the underlying functionality of this project 
other than some modifications to SQLite
scripts to improve performance.

I will make those adjustments again and report on the outcome.

I do not believe it’s anything I have done.

I believe (no proof) that something within LC has corrupted the project.

I have looked at copying the old project into a new project but that within LC 
seems to be a nightmare scenario.

If that was easy and it worked it would be a future solution or if there was a 
livecode maintenance type project that could do this sort of thing that would 
be good.

All the best for now.

Will report back

Thanks

Terry

Go to card has become slow

[Terence Heaford via use-livecode]

I have a project that opens at a particular card.

When I go to another card (any card) it’s very snappy.

When I return to the original card (from any card) I have noticed a second or 
two delay before it happens.

There would appear to be nothing in any script that would account for this.

Can anyone give some insight as to why this has happened?

I reinstalled LC to no avail.

Community 9.5.1

MacOS 10.15.4

I read something about font changes on the forum but that seemed to relate to 
iOS not MacOS.

I’m at a loss

Re: Ordering text

[Terence Heaford via use-livecode]

I agree that is why I have concluded to do the calc in LC.

However, I can’t store the balance one time in SQL as the balance value changes 
depending on which records are selected and the sort order(which may be by 
different columns).

So it is not just a schema issue, it started out as a LC issue because LC doing 
a "put text before” vs a “put text after” has real performance issues.

If you read my solution which is a bit of sqlite (sum) and then do a “put text 
after” it sorts out the bottleneck which is actually in LC’s (put text before).

I tried put merge("SELECT *,SUM (amount) OVER (ORDER BY recID) AS balance FROM 
myAccountName") into tSQL in response to a suggestion in this thread and so 
others do not wander down a dead end posted my result which shows that it has 
poor performance. Whether that is as a result of LC’s SQLite implementation or 
just SQLite I do not know.

Thanks for your interest and suggestions.

Best Regards

Terry

Re: Ordering text

[Terence Heaford via use-livecode]

This actually works but is very slow (> 800ms)

put merge("SELECT *,SUM (amount) OVER (ORDER BY recID) AS balance FROM 
myAccountName") into tSQL

I have settled on my earlier suggestion


Earlier suggestion results in 20ms performance.

-
I believe it’s sorted (forgive the pun)

As the data is stored in an SQLite db I have used the db to sum the values then 
worked from the top. Like below.

This results in approx. 20ms for each sort direction.

I have looked into a running total calc using SQLite but the solutions I found 
seemed rather complicated.

Sometimes asking for help then presents a solution.




Thanks

if tOrder is "desc" then

put dbGetAmountForAccount (pAccountName) into tBalance

repeat for each line tRec in tData

put tBalance into item 7 of tRec

put item 6 of tRec into tAmount

subtract (item 6 of tRec) from tBalance

put tRec & CR after tCellData

end repeat

delete last char of tCellData

else

repeat for each line tRec in tData

add item 6 of tRec to tBalance

put tBalance into item 7 of tRec

put tRec & CR after tCellData

end repeat

delete last char of tCellData

end if

Ordering text

[Terence Heaford via use-livecode]

I have approx. 7000 lines of tab delimited data.

When I execute the code snippet below if the sort order is descending it takes 
approx 120 milliseconds otherwise it takes 20 milliseconds to process.

Can someone explain why and perhaps come up with a faster solution.

Thanks

Terry
——

repeat for each line tRec in tData

add item 6 of tRec to tBalance

put tBalance into item 7 of tRec


switch tOrder

case "desc"

put tRec & CR before tCellData

break

default

put tRec & CR after tCellData

end switch


end repeat


switch tOrder

case "desc"

delete char 1 of tCellData

break

default

delete last char of tCellData

end switch

Re: Object Fonts

[Terence Heaford via use-livecode]

I may have found the problem.

Datagrid helper. When I used that it changed to my selection.

Does this mean Datagrid Helper changes the font in a different place than LC 
IDE?


Thanks

Why can’t I choose Helvetica Neue as an object font?

Whenever I do it turns out italic.

Re: Table Text Livecode vs .....

[Terence Heaford via use-livecode]

Here’s another interesting observation.

My table is set to Lucida Grande 13

I have some popup menus on the card set to Lucida Grande 13

Why does the text in the popup menus appear larger than the text in the Table?


Thanks

Re: Table Text Livecode vs .....

[Terence Heaford via use-livecode]

The setAllowsFontSmoothing function states

"Font are smoothed if they are antialiased when drawn and if font smoothing is 
both allowed and enabled. For information on how to enable font smoothing, see 
the setShouldSmoothFonts(_:) 
<https://developer.apple.com/documentation/coregraphics/cgcontext/1455816-setshouldsmoothfonts>
 function. It is not usually necessary to make changes to both parameters at 
the same time; either can be used to disable font smoothing.”

I have the "use font smoothing when available" checkbox ticked in the General 
Preferences. The above suggests that LC does not have these settings enabled.

As I said previously a user function to set this would be beneficial I believe.

What about it mothership?

I wonder if there would be a performance hit for providing this functionality?

Thanks

Re: Table Text Livecode vs .....

[Terence Heaford via use-livecode]

Firstly I have an iMac, none retina.

1. Just checked Pages & Numbers and they both appear similar to LC.

2. Then checked TextEdit and that appears the same as Filemaker.

The rendering of the text in Filemaker & TextEdit appears to my poor eyesight 
to be more black (if that is possible).
My poor eyesight is the reason I notice this in the first place, because I have 
the same database in both LC & Filemaker.
I prefer the scripting of LC to Filemaker but the display of the same table is 
much clearer in Filemaker for the same font (more blackness).

Perhaps there is an anti alias setting or such like, that has not been 
implemented in LC.

If so it would be good to get that option?

There used to be (not sure if it’s there now) a terminal command

defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

and probably others for this sort of thing. Perhaps they have to be implemented 
in app.

Re: Table Text Livecode vs .....

They are both Lucida Grande 13. One is Filemaker the other Livecode.

All Apple’s apps and those that clearly using Native Text display the same it 
is only Livecode that displays differently.

Does Livecode use Apple’s text rendering or another?

Thanks

Re: Stack Height/Menubar

Hi Klaus,


What an excellent suggestion.

Copied my menubar to a card that I never use and pointed everything to that and 
its associated scripts and this has now sorted the problem.

Named my Card “MenusAndImages”. Keep my button icons here as well.

Sorted.

Thanks for your help

Re: Stack Height/Menubar

[Terence Heaford via use-livecode]

This is fair enough but you still cannot put anything in the bottom 22 of a 
visible card on screen.

Try dragging an object to the card and it will not allow you to place it in the 
bottom 22 of the card (LC 9.0.1)

Thanks

Stack Height/Menubar

[Terence Heaford via use-livecode]

This post is regard the use of Livecode on MacOS(LC 9.0.1)

When you set the height of this stack to 800 (for example)

The height of this card in the property inspector is 822 and is also returned 
as 822 in script. 

This seems to be as a result of the menubar position on none mac systems.

I have "set as stack menubar" checked in Menu Builder

When displayed on screen the card displays with a height of 822 not 800 even 
though the menubar is not showing in the window.

If you then position say a button for example within the lower 22 of the card 
remnants of the button can be seen on other cards when you go to another card.

How is this supposed to be dealt with in Livecode.

It all seems rather confusing to me.

It is usual on a Mac to have a 20 border to the edge of windows etc. As stated 
above if you do this then parts of the buttons
for some reason show on other cards (22 - 20).

Livecode should simply identify you are on a Mac and the 22 for the menubar 
should be dealt with in Livecode code rather than leaving it
to the scripter to sort out.

On a Mac if you set the stack height to 800 then the card should default to 800.

Why can’t the menubar be stored by some other means?

End of part rant.




Thanks

Terry

It’s weird but placing this in the preopenCard script sorts out the issue for 
now.

set the dgProp[ "column labels" ] of group  “myTable" to the dgProp[ "column 
labels" ] of group "myTable"


All the best

Re: DataGrid Column Labels

[Terence Heaford via use-livecode]

I see what you have done and when I create a new project with LC9 and create a 
Data Grid I do not have any problems.

The issue I have is when I create a Data Grid within a project that has been 
created with an earlier version of LC.

If this is relevant I do not know.

For the moment I have settled on placing this in the preOpenCard handler


put  “aa,bb,cc,dd,ee,ff,gg,hh" into tFields

replace "," with CR in tFields

set the dgProp[ "column labels" ] of group  “myTable" to tFields



This does the trick but it would be better if I knew why?

There are 13 Data Grids in the project.

8 that were there before LC9 are OK the other 5 exhibit the issue. 



All the best

Terry

Re: DataGrid Column Labels

[Terence Heaford via use-livecode]

More investigation.

Instead of using DGH to change the header label I did it manually by editing 
the groups.

This worked until a reload of the project at which point the header label had 
disappeared again.

Upon working through the header by editing the groups you eventually come to 
the text field that contains the header text.

This was empty.

Clearly something in the script of the DataGrid is emptying that field.

At this point I am giving up although if you create the headers on opening the 
project with the likes of:

set the dgProp[ "columns" ] of group  “myTable" of cd  “myCard" of stack  
“myStack" to "test"

set the dgProp[ "column labels" ] of group "myTable" of cd "myCard" of stack 
"myStack" to "TEST"


Then they do seem to stick for the duration of the project being open. I have 
placed these in open stack


All the best

Re: DataGrid Column Labels

[Terence Heaford via use-livecode]

When I look at the Data Grid Templates in the project browser I see 2 tables 
that refer to DG2.

I suspect these are the culprits because these are associated with the two new 
tables I have added to the project.

Where there problems are, I don’t know.

Re: DataGrid Column Labels

[Terence Heaford via use-livecode]

Thanks

Will have a look at that although the column does not have a column behaviour.

I have changed the properties of the header with DGH but the props listed in 
the Property Inspector do seem correct.

If I go back into DGH and click on the green tick to accept a change of margins 
for the header, the label again shows until the next time I restart the Stack 
in LiveCode
at which point it disappears again.

I can’t see what I have done to cause this errant behaviour.

There must be a bug somewhere but where…?

DataGrid Column Labels

[Terence Heaford via use-livecode]

I have just started having an issue with the Column Labels on some newly 
created tables.

Basically they do not show unless I press “Refresh Data Grid" in the Property 
Inspector.

If I then shut down LiveCode and relaunch it they have gone missing again.

I am using the community edition of LC9 in OSX 10.13.4.

It is only affecting newly created DataGrids.

DataGrids that have been created in previous versions seem OK.

My only solution has been to overlay the DataGrid with a label.


Is this an issue anyone else has been having or is it just me?

I have been using the DGH 2.0.0 plugin if that makes a difference.


Thanks for any pointers.

I just thought the correct way for this to work (auto with the horizontal 
scrollbar) should depend
on the width of the header rather than whether the table contains data and the 
width of the header.

DataGrid Horizontal Scrollbar

[Terence Heaford via use-livecode]

When I have a DataGrid with the show horizontal scrollbar set to auto the 
scrollbar is hidden when the DataGrid contains no rows.

On the face of it this seems correct but when the DataGrid header is wider than 
the window the scrollbar is still not visible and hence it is not possible to 
see the header contents
without enlarging the window.

Is this the intended method?



Thanks

Terry

 Submitted again due to incorrect address  
 Apologies for previous post 


I was just trying out LC9 DP11 and noted in the LC Blog that Datagrid2 is 
available for testing.

I am a little confused because on opening DP11 I could only find the previous 
Datagrid.

Is DG2 a widget or rolled into the old Datagrid format?

Is DG2 available in the community edition?

Could someone help me understand please so I may try it out.

That’s cracked it.

Thanks very much to everyone who has contributed.

Not thought about this much but is having the print margins default to 72 the 
best option for most situations?
This is one for better minds than I.

Anyway, thanks again to all.

Hi,

Thanks for your suggestion but I am afraid it’s not working here:

I have prepared a short movie on dropbox so you can see what happens when I 
print it and then open as PDF in MacOS Preview.

Not sure at all what is going wrong. Could it be something to do with the 
scaling in the amCharts example?

Re: Capturing screen into image

[Terence Heaford via use-livecode]

Thanks for your help.

I have changed the script to below and it does not work.

set the lockLoc of image "myImage" to false
export snapshot from rectangle (the rect of widget "Browser") to pictVariable 
as PNG
put pictVariable into image "myImage"
set the width of image "myImage" to the formattedWidth of image "myImage"
set the height of image "myImage" to the formattedHeight of image "myImage"
print card from topleft of image "myImage" to bottomRight of image “myImage"

The image “myImage" on the screen seems to be the same as widget “Browser”
but the print card line of the script shows the grey bar at the top.


Any other ideas please.

Thanks

Terry

Re: PrintPaperRectangle

[Terence Heaford via use-livecode]

Thanks for your explanation. It does seem logical.

But where does 587 come from in 8,8,834,587 ?

A4 is 553.

Thanks

Terry

Capturing screen into image

[Terence Heaford via use-livecode]

This script does not work.

export snapshot from rectangle (the rect of widget "Browser") to pictVariable 
as PNG

set the rect of image "myImage" to the rect of widget "Browser"

put pictVariable into image "myImage"

print card from topleft of image "myImage" to bottomRight of image  “myImage"


After placing the captured image into “myImage” there is a grey bar at the top 
and the full width of the image is not visible.

Am I doing something wrong?


Thanks

Terry

PrintPaperRectangle

[Terence Heaford via use-livecode]

LC 8.1.4, MacOS 10.12.5

Print Paper Rectangle returns 8,8,834,587 for A4 Landscape.

This does not seem to match the description in the dictionary?

"The printPaperRectangle property contains four comma-separated integers and is 
in points.
The default value reflects the default values of the printPaperSize and 
printPaperOrientation.
The four numbers represent the left, top, right and bottom of the rectangle 
being printed to.
The rectangle is relative to the top-left of the page, and the left and top 
will currently always be 0.”

Can anyone shed some light on this please.

Thanks

Printing a Widget Browser

[Terence Heaford via use-livecode]

Not posted for a long time but still keeping an eye on progress.

Is there any chance of printing a Browser Widget any time soon?

This code just gives a grey printout.

I am waiting patiently for this so that I can use for example amCharts within 
LiveCode.

I have implemented a print routine by exporting to an image but as this is an 
image it can turn out blurred.

Thanks

Terry
