Hi Dragos lonal:
I didn't mention they have readonly attributes. How can we remove
readonly attribute?
Thanks for reply.

verticalLoc and x are readonly values, you cannot assign them.
use the frame property, first to retrieve it, change the x value and
then to reassign to the button.
something like
CGFrame frame = pPngButton.frame;
frame.x = ...;
pPngButton.frame = frame;

Hi:
Thank you for your reply.
Oh yes. It an Objective-C class.
regardless I place (bVerticalDisplay == YES) or not. The function
silently fails, with no warnings.
The I decided to
pPngButton.verticalLoc.x = (bVerticalDisplay == YES) ? 250 : 410;
This time I got warning.
error: lvalue required as left operand of assignment
Many thanks

Hi:
I have a struct
@interface PngButton : UIButton

@public
bool OffPos;
CGPoint horizontalLoc;
CGPoint verticalLoc;

@property (assign) bool OffPos;
@property (assign) CGPoint horizontalLoc;
@property (assign) CGPoint verticalLoc;

No, you have an Objective-C class.
PngButton* pPngButton = [PngButton
buttonWithType:UIButtonTypeInfoDark];
[pPngButton setFrame:CGRectMake(screenRect.size.width - 70.0, 50.0,
36, 36)]; // No problem
pPngButton.verticalLoc = CGPointMake((bVerticalDisplay == YES) ?
250 : 410, 50.0);
I get an error
error: lvalue required as left operand of assignment
Why it is not working? I shouldn't get this error.
Any help will be very much appreciated.
Do you get any warnings?
Try this and see what happens:
pPngButton.verticalLoc = CGPointMake((bVerticalDisplay == YES ?
250.0 : 410.0), 50.0);
