Using LL22 I’m handling the LL_CMND_GETSIZE_USEROBJ to try to alter the size of a custom-drawn field. I’m casting LPARAM TO scLlDrawUserObj and then modifying scLlDrawUserObj._rcPaint to set the size of the field. However when I get to the LL_CMND_DRAW_USEROBJ handler for the field size is unaffected.
Should I be setting anything else besides _rcPaint in scLlDrawUserObj? Should I be returning anything other than 0 for LRESULT?
Thank you!
Hello Erik,
thank you for your post.
Can you try to handle LL_CMND_GETSIZE_USEROBJ_SCM instead and pass the required size in SCM units (1/1000 mm)? Can you try to set the width and height of your drawing to UnitFromSCM(DrawingWidthSCM(…)) and UnitFromSCM(DrawingHeightSCM(…))? Otherwise, it might also be feasible to just use a formula for the width and height and pass the required values as additional fields.
