 2011-01-08 16:41:55 +01:00
Přemysl Eric Janouch 909a0352cc Don't draw the grid when it would be too narrow.

just in our own namespace.
 2011-01-06 13:07:04 +01:00
Přemysl Eric Janouch 53d1de680d Change symbol clip tolerance to widget units.

Přemysl Eric Janouch 25f1186000 Draw selected objects with another color.

of the document to the selection issue a warning.
 2011-01-05 01:11:03 +01:00

Přemysl Eric Janouch d3e5483c84 Make adding symbols to the diagram possible. 
This required creating a simple framework for operations to LdCanvas.
It is probable that it's going to require some changes when other
operations are added. The basic idea behind it seems to be good, though.
 2011-01-04 09:54:05 +01:00
Přemysl Eric Janouch 713f2821e4 Fix the desktop file.

Přemysl Eric Janouch f2f308f2f5 Make the symbol menu grab focus. 
This way when the user clicks outside the menu when it is open,
the menu will close itself first.

Keyboard input is however still not handled.

The symbol menu should be redesigned.
 2010-12-18 05:01:50 +01:00
Přemysl Eric Janouch 86e73f86c2 Rename LdDocument* to LdDiagram*.

 2010-12-11 14:26:00 +01:00
Přemysl Eric Janouch afacad693d Add a main toolbar. 
So far it has no special powers. This should change in the future.
