STM32 embedded GUI library - icon problem

Hi everyone!

I try to use STM32 embedded GUI library ( http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/PF257934 ).  I use STM32F103Z with 64kB SRAM, and LCD with SSD1289 controller. I have one problem. All functions work, almost. I can't use icons like buttons. I started demo applications but it is not working there too. Can anybody tell me how to fix this? I think the problem is there: if ( CompareCoordinates( tmpCoord.MaxX, tmpCoord.MaxX - tmpSize.Length + 1, tmpCoord.MaxY, tmpCoord.MaxY - tmpSize.Height ) )               {                     ...               } because function never goes into ''if'' block. #stsw-stm32098 #stm32-embedded-gui

I think the problem is there:

if ( CompareCoordinates( tmpCoord.MaxX, tmpCoord.MaxX - tmpSize.Length + 1, tmpCoord.MaxY, tmpCoord.MaxY - tmpSize.Height ) )              {                    ...              }because function never goes into ''if'' block. So the function must be never returning true - mustn't it?Have you tried evaluating the parameters you're passing it? Is the function actually returning the correct result based on those values?Can you step into the function?
