Qgtk2.pas - quick programming in Pascal with gtk2 libraries

index

Freepascal allows you to use gtk2 libraries for X-windows or even for M$ windows. The usage of gtk2 libraries is rather complicated and it usually takes many weeks to learn it. The unit qgtk2.pas makes the usage of gtk2 simpler and quicker. Although it doesn't give you the possibility of using all the features of gtk2 it will be sufficient enough for many easier programs.

Requirements:

freepascal 2.x ( http://www.freepascal.org/ ) Linux, X11, gtk2 or M$ win32 and gtk2 dll

(Old Gtk1 version for freepascal 1.1: gktk.pas- 243 Kb. and for M$ win gtk1.3 dll library)

Program hello word:

With qgtk2.pas it is really very simple:

uses qgtk2;                                                                      
begin                                                                           
qstart('Hello Word!', nil, nil);                                                
qLabel('  Hello word with ');                                                   
qButton(' QUIT button ', @qDestroy);                                            
qGo;                                                                            
end.

qpack.pas

Easy putting components into a window:

If you call the procedures of the components (qlabel, qbutton, ...) the components are placed side by side in one row from left to right in the order they have been called. After the call of the procedure qNextRow the following components are placed in the next row. The procedure qFrame enables to place the components in the collumns.

qLabel('Hello'); qButton('qButton', nil); qLabel('and qLabel');                 
qNextRow;                                                                       
qLabel('1 qNextRow  qLabel'); qButton('and qButton', nil);                      
qFrame;                                                                         
qButton('2 qFrame',nil);                                                        
qNextRow;                                                                       
qlabel('3 qNextRow in frame -'); qLabel('and qLabel');                          
qseparator;                                                                     
qlabel('4 qseparator in frame'); qButton('and qButton', nil);                   
qFrame;                                                                         
qLabel('5 qFrame'); qButton('and qButton', nil);                                
qNextRow;                                                                       
qLabel('6 qLabel       ');                                                      
qEndFrame;                                                                      
qLabel('7 qEndFrame'); qButton('and qButton', nil);                             
   qButton('...', nil); qButton('and QUIT', @qDestroy);

Many components and windows:

Easy creating of menus, dialogs and another componets.

The graphics:

It allows you to draw the essential graphics and to show xpm pictures. It supports the movement of the pictures without blinking and with the transparent color and it enables to react on the position and click of the mouse.
