Hi All,
I have a bit of a problem. This is happening with GTK2.
I have a StringGrid where when the column header is clicked on, a
ComboBox appears in the header in the dropped down state. The
dropped
down state is done in the mouseDown event of the StringGrid by
doing
ComboBox.DroppedDown := true .
The Combobox only stays dropped down while mouse is down.
Preferably I
would like it to stay dropped even if the mouse is released, and
only
close when a selection is made.
The other more serious problem is that once the ComboBox is used, I
cannot select anything else outside of the StringGrid. I guess what
must
be happening is that once the ComboBox pops up it steals the mouse
from
the StringGrid, with no proper finish on the StringGrid side of it.
Is there something I can do to get around these problems ?
To note, If I do not have the ComboBox show in the dropped-down
state by
doing DroppedDown := true, these problems do not happen, but then
you
have to click to have the ComboBox to have it appear and click
again to
have it drop down. Not what I want.
BTW, this code runs OK on Delphi with ComboBox staying dropped down
and
proper mouse release.
Thanks,
George
Have you tried this in windows?
With Laz/Win32 the behavior is fine, like in Delphi, the drop-down stays
after mouseUp and I am able to select other things afterwards.
With Laz/GTK1 I can't say because ComboBox.DroppedDown := true function
does not make the ComboBox appear dropped down, so it's the click to get
the Combobox and click again to drop it down behavior, and I am able to
select afterwards, like in GTK2 when I don't use the DroppedDown function.
George
