For the icon-path (that rows of icons over the browser) of Xws, I'm using
a NSMatrix in the NSRadioModeMatrix mode.
To start dnd from a selected cell I've used:
- (BOOL)trackMouse:(NSEvent *)theEvent
inRect:(NSRect)cellFrame
ofView:(NSView *)controlView
untilMouseUp:(BOOL)untilMouseUp
But, updating from cvs, I noticed that, now, only the NSTrackModeMatrix
and the NSHighlightModeMatrix modes let me use this method.
>From the Apple documentation:
"
NSTrackModeMatrix:
The NSCells are asked to track the mouse with
trackMouse:inRect:ofView:untilMouseUp: whenever the mouse is inside their
bounds. No highlighting is performed.
NSHighlightModeMatrix:
An NSCell is highlighted before it's asked to track the mouse, then
unhighlighted when it's done tracking.
NSRadioModeMatrix:
Selects no more than one NSCell at a time. Any time an NSCell is selected,
the previously selected NSCell is unselected.
NSListModeMatrix:
NSCells are highlighted, but don't track the mouse.
"
It seems that only in the NSListModeMatrix mode, the cell doesn't track
the mouse!
But, if the last changes to NSMatrix are correct, how can I intercept the
first mouse-down in a cell to test if it is the start of a dragging,
before let it send its action?
Please help me because this problem is stopping all my work.
Thank you
Enrico
