Hi, I am working on a project using the LPC1788 and NXP's version of emWin. I would like to use GUIBuilder for the window layout but there seems to be a few perplexing limitations. Is it possible to draw a graphical line in GUIBuilder? How about a rectangle with rounded corners?

Any advice would be greatly appreciated!

Dustin

From my experience, the GUI Builder is quite limited. For anything beyond basic widget placement and some initialization (e.g. font selection) you have to dive into the code it generates.

Ive mostly used it to start a window, saved it and then opened it in the IDE to finish it.

Mixing 2D drawing and widgets is something Ive only tinkered with so far. From my understanding you have to add a WM_PAINT case to the window callback function in which you call WM_DefaultProc to draw your widgets for you then call your drawing function for the 2D stuff.

E.g.

case WM_PAINT:
WM_DefaultProc(pMsg);
Draw2D();
break;

Hi Friend,
I dont see any requirement for drawing line in GUI Builder, as emWin provides API's for the same. Even there is an API for rounded corner rectangle. I am using LPC1788 with emwin able to draw all the geometric line drawings. Though i agree that builder has got lot's of limitation but using full emwin API's you can easily create decent user interface.
Thanks!!
