[Gambas-user] [gambas-user] Possible bug in gb.gui

[Paul Horechuk]

OK, then let's rephrase that slightly. The gb.gtk component does not 
behave the same as the gb.qt4 component. If I disable the capability to 
autodetect the environment and force the use of gb.qt4, then everything 
works. Hence, the problem is within gb.gtk. As part of setting the taget 
environment then I have to install the base qt4 libraries as a minimum, 
or install perhaps a full KDE desktop.

The attached file is a source archive. Don't worry about the database 
option. Fill in the /Issued To/ field, the /Job #/, the two dates, and 
set the count to something like 3 or 5 so that you get an odd number of 
labels. You will need external access to qrencode and phpcli. When the 
fields are being filled, the on-screen QRcode will update. When 
complete, click the OK button and either Preview or Print. Preview is 
recommended. Open a file manager and navigate to the QRcard directory 
and open QRpicture.png. Card #3 is correct and the others have valid 
QRcodes, but bad text.

As mentioned, it works under several desktop environments with gb.qt4, 
but using gb.gui and allowing the auto selection of gb.gtk fails.

There is nothing fancy in the components, except for gb.qt4. I do use 
gb.db, gb.mysql, and gb.odbc, but these should not be an issue without 
the /Use Database/ option selected.
