I'm trying to make a canvas, where I should be able to put, select, move
element and so on.
You can find attached a first test for this canvas.
It uses a gtk.Layout and it seems to work, but I'm having difficulties
to enhance the interface.
- I want to be able to select elements by drawing a box with the mouse.
For this, I'm using DND signals, and I've added a gtk.Image to the
The image is updated when the 'drag-motion' signal is emitted.
But this is really slow.
-> Is there a best way to do it ? Have you any idea to improve it ?
Besides, using DND signals helps a lot, but I didn't find how to
tell GTK not to use any drag_icon.
So, I'm using gtk.STOCK_CUT as icon, but it doesn't have sense
-> Is there a way to tell GTK not to use any drag_icon ?
- I want to be able combine selections when <SHIFT> or <CTRL> are pressed
This works when I select one element with left click, but with
I've got problem with box selection, because <SHIFT> key seems
to cancel a drag n drop.
-> Is-there a way to prevent <SHIFT> key from cancelling a drag'n'drop ?
- I would like to bind some shortcuts to specials keys like <del>,
<backspace> or <pageUp>
I created a Popupmenu and I would like to use ActionGroup but I
don't find the accelerator name corresponding to theses specials keys.
-> Is there a way to bind <del> and <backspace> keys ?
Don't hesitate to comment my code, I'm not very familiar with programming.
