Re: [MSEide-MSEgui-talk] Application paused if no mouse event.

Ha, ** VERY MUCH ** better. ;-)

---> No more underrun error, no scratch when opening dialog files, no
scratch when switching float<>tab or opening/closing forms.

Synchronization: perfect. (maybe even better than fpc-queue()).

OK, re-come back to {$DEFINE mse} when using uos (that was updated, of
course).

Well done Martin.

Re: [MSEide-MSEgui-talk] Maximum length of array of cfloat ?

[fredvs]

Hello.

Yep, I get it ;-)

To detect the BPM of a audio file, first that file must be converted into a
buffer of samples.

This is done by a other thread.

But, on my system, after decoding +- 1 mega, the conversion become slower.

I did use a pause(length_of_file div ratio) before to use the converted
buffer to get the BPM.

But pause(length_of_file div ratio) is not enough when the audio file > 1
mega and the buffer is not fully completed.

The trick was to use:

while not thread_terminated do pause(100);

That way, the buffer is completed before to use the GetBPM function.

And it works perfectly now ;-)

Sorry for the noise.

Thanks.

Because the wrong value is still there (if not corrected).  And the mix is
done by a timer of 100 ms.  So when the mix occurs, each 0.1 second there is
a modal error message (no time to close it).  And finally it crash.

Hello Martin.

I battle hard with id3 tag. (http://id3.org/Home)

id3 version 2 is in the pocket >

var
   BufferTag: array[1..128] of char; 
F: file; 

 begin
 AssignFile(F, '/test.mp3'); 

  Reset(F, 1); 
   Seek(F, FileSize(F) - 128); 
   BlockRead(F, BufferTag, SizeOf(BufferTag)); 
  
 CloseFile(F); 
 writeln('tag : ' + copy(BufferTag, 1, 3)); 
 writeln('title : ' + copy(BufferTag, 4, 30)); 
 writeln('artist : ' + copy(BufferTag, 34, 30)); 
 writeln('album : ' + copy(BufferTag, 64, 30));

 writeln('comment : ' + copy(BufferTag, 98, 30)); 
 writeln('genre : ' + inttostr(ord(BufferTag[128])));

end;

Now time for something not so easy... ---> id3 version 3 and his image tag.

I have already something.

But how could I show those picture data with MSE?
If I have a buffer filled with picture data (png or jpg), how to use that
buffer to show the image ?

Thanks.

Ok, valuemax = 99 and valuemin = '' .

Now, if for example 200 is entered ---> reset to 100.
And if  value = '' or < 0 --> reset to 0.

Perfect.

Yes, but for lazy people (like me) it is lot of work to press a key.  ;-)

Also, because the message-form is modal, if a process is running that needs
to access value of the spinedit, it can make trouble if the message-form was
not closed.

Also, in the case of StrumPract, if auto-mix is on, if a not valid value is
entered (and not auto-corrected), it can crash the program when the mix
occurs.

All that to say that with MSErealspinedit and all his features, I have all
to do like I want.

Perfect.

Hello Martin.

OK, I I have kept the philosophy of MSEgui.

But I did change only one thing: in place of a modal error-message (that
need to manually be closed), I use a hint-timed-form (that closes it-self
after 2 seconds).  And to avoid crash, the wrong value is corrected (it is
commented in the hint-timed-form) .

Re: [MSEide-MSEgui-talk] trealspinedit and valuemin/valuemax ?

[fredvs]

> It contradicts the value entry philosophy of MSEgui

OK, I understand but maybe it could be good, if for example a new value >
valuemax is entered, that a error range message is displayed (like MSE do
now) but after the old value before changing is restored.

For example if you assign:

valuemax := 100
valuemin := 0
value := 50

And a user enter a new value --> 200.
It will be a error range and after closing the error message, the new value
(here 200) will be still in the edit-frame.

IMHO, I would prefer to restore the old value (here 50) after the error
message.

Or maybe restore the defaultvalue in place of the old one

My 0.0009 cents..

Thanks.

Ha, good to know (and to add to the hint text of a spinedit).

Perfect Martin.

(But I think that I will use "ontextedited" to check-correct value and a
kind of timed-hint-message-self-closed-form to explain the error value
entered).

[fredvs]

Hello Martin.

I do not like that pretentious and stupid JosephMcc

The good news is that I will use a other Linux distro.

What do you recommend?

They want that a template is filled, not sure how to fill it:

```
 * Cinnamon version (cinnamon --version)
 * Distribution - (Mint 17.2, Arch, Fedora 25, etc...)
 * Graphics hardware *and* driver used
 * 32 or 64 bit

IMHO, like you Julio, I think it is hopeless.

Martin, do you remember the  "soname" bug in fpc ?
How many posts did we sent in fpc-mailinglist?

The problem with gurus is that it is impossible for them to recognize a
error or that they do not understand the issue.

Did you remember that in fpc-bug-tracker, for that "soname" bug, even
Florian agreed to fix it?
But marcov, the Big guru refuse to fix it (because so he must agree that he
was wrong).

The same appends for me in FreeBSD forum.
All the proves were there (that the multi-arch design of FreeBSD is
incompatible with their linker+garbage manager).

Those people does not want to read your explanation because they could note
that they are wrong.

ICCCM recommended methods ?
This to help those distros-test sites to do their own test+result.

IMHO, a label like "This distro is conform with ICCCM" should be very useful
for people that choose a Linux + Xorg distro.

container.frame.scrollpos_x := container.frame.scrollpos_x + 100;;

No, only 20 %. 

Sorry, I do not understand how scrollpos works.

For example, if a Tslider.width = 16 * parent_form.width, how to jump to the
3th page (if each page = 1 form.width) using the scrollbar by code ?

Ha, thanks. (But what is this ?).

Yes, after more concentration I did remember why.

In the past, when using docked forms into main form, the focus of Object
instector was loosed.

But it was fixed (but did not know) in 2016.

By the way, that Esc feature makes life easier.

Ok, changing

with 

tdockpanel1fo = class(tdockform)

Fixes the "1" auto-added for title-form.

There is still a problem with vertical scrollbar that will not appear if the
height of container > height of dockform .

(And this is not a joke).

OK, I did follow your order:

3) Delete the files of extra-dockform in StrumPract.
4) Re-create those extra-dockform from scratch + paste older-code.

6) ;-)

msedockform_scroll_ok.mp4

  

Ok, solved.

OK, I get the active form in tab with basedock.dragdock.activewidget and if

All works perfectly.

But, when a tab is changed, the title of the the tdockpanelform is changed

How to keep the original assigned title (not this automatic change) ?

[MSEide-MSEgui-talk] Form accessible via form-designer ?

[fredvs]

Hello Martin.

In MSEFormDesigner, when a form is covered, for example by a tdockpanel, the
Object inspector cannot be accessed via the form designer-click-on-widget.

It must be done with the list in Object inspector.

The same for each widget that accept childs.

Would it be not good to have the possibility to add a icon on the form, like
for NoGui widgets?
While clicking one those icon, it will select in Object inspector the
correspondent widget, like when clicking on that widget. 

Of course that "Show Parent-icons in Form Designer" could be optional.

 

What do you think?

As workaround, here a way to hide the maximize button and not maximize if

procedure tmainfo.updatelayout();
begin

bounds_cxmax:= 0;
bounds_cxmin:= 0;
bounds_cymax:= 0;
bounds_cymin:= 0;

... // do the resize things if needed...

bounds_cxmax:= bounds_cx;
bounds_cxmin:= bounds_cx;
bounds_cymax:= bounds_cy;

[fredvs]

Hello Martin.

I am a little afraid about the resource used by tprogressbar.

Included a simple demo to show it.
msemem.zip
  

The tprogressbar.value is assigned by a timer with a random value:

When rendering the tprogressbar: cpu used = 70 %.

 

Without rendering the tprogressbar, cpu used = 28 %.

 

Is there a other-less-resource-used way to mimic a  tprogressbar ?
Do you think that drawing on a custom canvas would need less resource ?

Thanks.

Fre;D

Re: [MSEide-MSEgui-talk] Tprogressbar and resource used ?

[fredvs]

Hello Martin.

Ok, I did test Tchart vs TProgressbar.

My verdict is:

- If TProgressbar does not have fading and frame is original (not use a
template) and not = nil (only a "pure" ) then the ressource
used by 20 TProgressbars is more or less equal than ressource used by 1
TChart of 20 bars.

- If TProgressbar use fading or frame is custom ===> much more ressource
used than a Tchart.

Some questions:

What is mwcnoise() / flo64($) ?
Is it a alternative to random() ?

Is it possible to have a TChart with only verticals bars (not linked like in
demo) that mimic a TProgressbar ?

Here updated demo that uses both TProgressbar and/or Tchart.

msemem.zip
  

Thanks.

Hello Marin.

How to fit all the bars in a TChart ?

On the picture, you may see that last bar is missing.
Changing for bigger tchart.width did not solve.

 

Included demo of this.

msemem.zip
  

Thanks.

Fre;D

PS: Indeed, Tchart uses less resource.

Yes, I know that Mint is not the best.
But, according to https://distrowatch.com, Mint is still the most popular
Linux distro.

IMHO, you should install it and test/adapt MSEgui for it.

Indeed, with original MSEide it works with left button.

I have to check ideU code.

Very, very, very sorry for the noise.

(And if you are not too angry, maybe you could give light where is code for

Re: [MSEide-MSEgui-talk] Form accessible via form-designer ?

[fredvs]

Hello Martin.

OK, I get it.

msedesigner_esc.mp4
  

There is only one bemol.

It is that I have to add a line in original formdesigner.pas.

In proc designkeyevent(), at line 3964, 
...
selectcomponent(comp1); 
  
activate; // this added

Otherwise, it is the Object Inspector that is focused and pressing Esc has
no effect.

With activate, the designerform has focus again and Esc works.

I would highly prefer to not touch to anything about
MSEFormDesigner/ObjectInspector/Components and always use the original but
here, I fall.

Or maybe for you adding "activate ;" at line 3964 in original code would not
be too painful...
formdesigner.zip
  

(But why the designerform-focus in loosed in ideU is a mystery).

That said, big Wow for this Esc feature (and of course the icon-parent-idea
has no interest any more).

Thanks.

Do you mean that the bug is fixed for  Gnome 3, Cinnamon and Mate ?

If yes, it should be fixed for Mint too because Mint uses Mate or Cinnamon.

[MSEide-MSEgui-talk] OnTabChanged ?

[fredvs]

Hello Martin.

On a tabbed form (currentsplitdir = sd_tabed) how to know that a other tab
(form) was selected ?

How to know what active form (=tab) is active ?

Is tdockpanelform the good choice for extra-dock panels?
 ( if you remember the StrumPract main form, I want to have others
dock-forms that have the same behaviour that the main-form ===> auto-height
when dragging a new form into the dockpanel and auto-height when the
dockpanel is tabbed and a other tab is selected.)

I was able to get the same behaviour as mainform of StrumPract for
extra-dockpanels with .currentsplitdir = sd_horz but with currentsplitdir =
sd_tabed the auto-height is not working.

Thanks.

Re: [MSEide-MSEgui-talk] How to use form-scrollbars ?

[fredvs]

Hello Martin.

Sorry, I do not understand the goal of clampinview.

Now about container.frame.sbhorz.pageup/pagedown.

With a simple demo-test it works.
This demo use the same waveform.pas than a other more complicated project. 

See attachment and video.

msescrolltest.zip
<http://mseide-msegui-talk.13964.n8.nabble.com/file/t2/msescrolltest.zip>  
msescrollpage_alone.mp4
<http://mseide-msegui-talk.13964.n8.nabble.com/file/t2/msescrollpage_alone.mp4> 
 

But inside a more complicated project, with same code, it does not work.

See video.
msescrollpage_strum.mp4
<http://mseide-msegui-talk.13964.n8.nabble.com/file/t2/msescrollpage_strum.mp4> 
 

The menu-items Up/Down to scroll use this:
(waveform.pas, line 239)

procedure twavefo.pageup(const sender: TObject);
begin
 container.frame.sbhorz.pageup ; 
end;

procedure twavefo.pagedown(const sender: TObject);
begin
container.frame.sbhorz.pagedown ;
end;

And there is no call to wavefo from outside, nor any timer working.
But you may see in video that scrolling by code works only once in
StrumPract.

If I may...

Since MSE has now also a huge assistive interface (and also because no other

Window Manager" like you said, Martin, a few years ago,

JWM (Joe Window Manager) has accepted in his to become assistive but... no
movement...

--> https://github.com/joewing/jwm/issues/331

And I am not talking about the tray-icons problems with lot of Window

May I propose to  change some values in mseconst.pas ?

If yes, here what I use:

en_modalresulttext: defaultmodalresulttextty = (...
'Y all' (vs All), ...)

en_modalresulttextnoshortcut: defaultmodalresulttextty =
'Yes all' (vs All), ...)

Included  mseconst.pas modified.

mseconsts.gz

Re: [MSEide-MSEgui-talk] MSElang news.

[fredvs]

Hello Martin.

Sorry for that question, but internet did not help me to  find a answer.

Does a program compiled by a lid of LLVM family need special libraries to
run ?
Or must a LLVM system be installed (like Java or Python do) ?

Re: [MSEide-MSEgui-talk] Cross compile from Intel 64 Linux to ARM 64 Linux ?

[fredvs]

Hello Martin.

The combat was hard but I win the war ;)

It works, Pascal code + fpc = Android native library that works.

For the people that are interested here how to do:

1) Use the Java arguments for all your exported methods like this (2 first
parameters):

procedure MyAndroidProc(PEnv: PJNIEnv; Obj: JObject); cdecl;   
begin
// do something
end;

2) Export your method using that name (maybe it is possible to change this
in Java calling class but that way it works):

 MyAndroidProc name 'Java_nameoftheJavaApplication_MyAndroidProc';

3) Compile your library with -Parm (for 32 bit) and -Tandroid parameters.

4) In your Android Studio project, create 2 directories and add your library
into it : 
- nameoftheJavaApplication/app/src/main/jniLibs/armeabi and 
- nameoftheJavaApplication/app/src/main/jniLibs/armeabi-v7a

5) In Java code android, add this code to force Android to compile only 32
bit application (fpc + android64 is not yet ready)

android {

defaultConfig {

ndk {
abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
}
}
}

6) Create a Java class with all the exported method of your library
(header).

7) In your main Java class, load the library with LoadLibrary().

8) Compile your apk application, transfer it to your Android mobile (with
Android Studio).

9) Enjoy.

Re: [MSEide-MSEgui-talk] Cross compile from Intel 64 Linux to ARM 64 Linux ?

[fredvs]

> Which compiler? 

FPC (or MSElang, of course).

OK, the people of CodeTyphon did a excellent work.
Their Cross tool chain work perfectly:

Target OS (-T) ---> Linux
Target CPU (-P) family ---> aarch64

OK, it works for cross-compiling Intel64 --> ARM64.

Target OS (-T) ---> Linux
Target CPU (-P) family ---> aarch64

Just needed to add this ARM64 libraries in the host os lib-search-path:
ld-linux-aarch64.so.1, libc.so, libdl.so and libpthread.so.

Then, with the help of the CT cross-chains, it compiles and works like
charm.

But this Java library works only on "pure" Linux ARM64 system.

For a Android ARM64 system, while trying to load the library, there is that
error:

java.lang.UnsatisfiedLinkError: dlopen failed: library
"ld-linux-aarch64.so.1" not found

So Android seems to not have ld-linux-aarch64.so.1 installed by default.

And even adding that library in the myproject.apk library folder did not
help.
(I do use Android Studio --> WoW).

The good news is that the ELF of FPC-Java-library is recognized and accepted
by Android.

The not so good news is that Android seems to use a other loaded than
ld-linux-aarch64.so.1.

So I did try with this parameters in FPC:

Target OS (-T) ---> -android
Target CPU (-P) family ---> aarch64

But when trying to compile with FPC there is that error:

Error: Illegal parameter: -Tandroid

So, to resume:

fpc -Tandroid -Parm ==> Compiles ok

fpc -Tandroid -Paarch64 ==> Compiles NOT ok ==> Error: Illegal parameter:
-Tandroid

Maybe fpc -Tandroid -Paarch64 is not ready yet...

PS: All advices how to create with FPC (or MSElang ) a Android native
library is welcome.
