Hi,
Can you help me to fix this problem.
I am customizing my table view to show various images in the background of
the cells accordingly as
Selected : Font Changed to While Colour, Background image, Highlighted.png
Deselected/Normal: Font -> Black colour, Bg Image: Default.png
I tried to override
- (void)drawInteriorWithFrame:(NSRect)theCellFrame
inView:(NSView*)theControlView
of NSCell to change the Font Color and BgImage according to the state as I
mentioned earlier.
Result: Once the application launched it is ok. Once I select col1 and
select col2, my Col1 still shows the Highlighted image, infact it is
deselected and supposed to show the Default Image. This because my Default
image is a transparent image. Even after overlapping Default.png on
Highlighted.png it is showing the same Highlighted.png.
I guess what I need to do is to remove the image from the Cell before
redrawing it. How to do I really don't know.
Kindly look into this and help me in this regards.
