[PD-dev] click-drag behavior

[Hans-Christoph Steiner]

One thing that often bugs me when editing is the click-n-drag behavior
of objects.  Here's the outline:

click and release unselected object
--------------------------------
* mouse down selects the object
* mouse up selects the text

click and release selected object
--------------------------------
* mouse down drags the cursor in the text
* mouse up does nothing

click and drag unselected object
--------------------------------

* mouse down moves the object
* mouse up releases the drag and selects the text

click and drag selected object
--------------------------------

* mouse down moves the cursor in the text
* mouse up stops that


I think that a better behavior would be this.  When an unselected object
is click-n-dragged, mouseup doesn't select the text or the object.  Then
you can move an object, then immediately move it again without having to
click to deselect it first.

This can be done with a 'moved' flag.  But I can't really find where to
put it, that code is pretty hard to follow (g_rtext.c, g_text.c, and the
widgetbehavior).  I attached my log of the pd-gui messages of the four
cases above.
