[Gambas-user] Displaying a pdf file to the user

[Jose Monteiro]

I know how to call an external viewer. Is it simple to show a one page pdf file 
inside a Gambas3 control?

[Gambas-user] Select and then unselect an item from a CollumnView

[Jose Monteiro]

Dear Fellows: In order to find an item inside a very populated CollumView, the 
user types an integer on a ValueBox and the search if made by:
cvNFMercantil.MoveTo(vbPedidoNFMercantil.Text)
cvNFMercantil[vbPedidoNFMercantil.Text].Selected = True
First problem: the item is selected, but the control does not "roll" to display 
it.Second problem: How can I unselect that item?
Thanks in advanceJosé Monteiro

Re: [Gambas-user] Gambas3 on Rasperry Pi 3 with Ubuntu Mate 16.04

[Jose Monteiro]

Hi guys, I am very interested on this matter too.So far, I know that is 
possible to install RaspBian (Debian for Raspberry) and then Gambas 3.8.2 : 
Gambas Documentation - /install/raspbian

  
|  
|   
|   
|   ||

   |

  |
|  
|   |  
Gambas Documentation - /install/raspbian
   |   |

 Can someone tell us if the installation goes smooth and if Gambas can work 
well with RaspBerry's IO?RegardsJosé Monteiro

 Hi all!

I tried to get Gambas3 running on a Raspberry Pi 3. I tried images of 
*Ubuntu MATE* (15.10 and 16.04) during the last three days!.

On the 15.10 I get a very old (outdated) Gambas3.5.4-2 from the 
repository running, which does not support newer code.

On both Versions (Ubuntu MATE 15.10 and 16.04) all efforts to get 
Gambas3 running from either *ppa:gambas-team/gambas3 *or**

*ppa:gambas-team/gambas-daily *failed to run:

Error message:

*gb.gui: warning: 'gb.qt4' component not found, using 'gb.qt5'**instead*

*libEGL warning: DRI2: failed to authenticate*

*Segmentation fault (core dumped)*


>From the list I have learned that*Ubuntu Mate*  ppas have problems.


How can I solve this?

a) on Ubuntu Mate 16.04

or

b) another Linux-image for the/*Raspberry Pi3*/
  that can run Gambas3 with the up-to-date version?


Thank you for reading this!

Greetings

When you use Chr$(10) instead, it will run as expected. The "\n" in 
Linux means Chr$(10), just like gb.NewLine.

If you had a Windows text file, it would be Chr$(10) Chr$(13) instead 
and you would have to delete both. But in a pure Windows environment, a 
"\n" would mean this automatically.

Re: [Gambas-user] Lenght of a string

[Jose Monteiro]

Thank you again.This one line solution is much more elegant.

 José,

A side note, no need also to use a FOR-NEXT to fill X spaces. You can do
it in a single step:

  'for i = 1 to (115 - len(name))
  '  name = name & Space$(1)
  'next
  name = String.Left$(name & Space$(115), 115)

If you need the spaces at the left (for example to right-align numbers),
you do the opposite:

  numberString = String.Right$(Space$(places) & Str$(number), places) 
'The number will be right-aligned to "places" spaces and returned in
numberString.

As Oliver pointed, you should use the UTF-8 versions of the calls;
otherwise you will have less than the expected characters in the
resulting string.

[Gambas-user] Feeding a DataView using data from another DataView

[Jose Monteiro]

Please guys, some help here.
I'm at the middle of a program for controlling a process for a chemical company.

1 - There is a DataSource linked to a table and containing a Dataview. The 
DataView will show hundreds of rows.

2 - There is another DataSource, which will use a sql statement, containing 
another DataView. This one will show a few rows, based on the sql statement.

The situation: When the user clicks on a certain row of the first DataView, I 
need to grab the value of the field Contract_Number so I can create the sql 
statement for the second DataSource.

The question: How can I grab the field value? There is no click event and the 
mouse down event, even with track enabled on DataView control, does not work.

[Gambas-user] DataView: how to know data of a certain cell?

Using Gambas 3.4.2, I've put two DataView's on the same window, first one 
connected on a table.
How can I grab the data of a certain cell, on a user selected roll?  I want to 
use this data to create a sql string and populate the second DataView.

[Gambas-user] Gambas in a tablet. Is it possible?

[Jose Monteiro]

I have finalized a software for a microbiological lab using Gambas 3. Right 
now, I am starting a new one for a chemical lab and had an idea: a main 
software on a desktop and clients on tablets, one for each technician, so they 
can input the results by the wireless network.

Is it possible to install Gambas over Android?
If not, is it possible to install a Linux distro on a tablet and have the touch 
functionality working well? Someone here already did it?

Re: [Gambas-user] Gambas in a tablet. Is it possible?

[Jose Monteiro]

Thank you Rob, for your quick reply.

A Virtual Machine as one of the possible solutions, you said? Interesting, but 
I guess free RAM would be a bottle neck. I could test this, for sure.

If a full Ubuntu ARM installation could preserve the touch screen functionality 
AND the virtual keyboard, this software is completely possible.

Maybe I need to think a little harder about it.

If you install an Ubuntu chroot or virtual machine, sure, just apt-get it.
None of the toolkits are optimized for touch but I assume Ubuntu has done
something to make Gtk touch-friendly for their stuff, since tablets are one
of their target platforms. So maybe it'd work with some judicious app design.

But there's no native Android Gambas interpreter yet, and without X or even
glibc, I'm not sure there ever will be. It would be almost as big a job as
a Windows port, which has been tried numerous times without getting further
than a proof of concept.

You can replace Android on many devices with a full Ubuntu ARM
installation, but you'll usually do so at the expense of some hardware
functionality, such as accelerated graphics or Bluetooth.
