I'm developing a grafcet editor, and I need to draw out of the node's bounds. The node is drawn as a ronded rect shape (one of the predefined shapes). Each node has associated four strings that must be written in the corners of the shape:


Text1 +--------------------------------+ Text2
| |
| |
Text3 +--------------------------------+ Text4

I created a derived class from NodeShape, and I overwrite the Draw method to call the base implementation and then, call a function that writes the strings and call the Repaint method with a rect that includes all modified area.

It seems that is working fine (nodes draw all strings) but, after that, the rest of the application don't repaints correctly (some buttons are not shown, grids don0t refresh its dat, etc). If I don't call the repaint method, the rest of the application repaints correctly, but the nodes are not shown complete (part of the text is not shown).

I have tried to use the CustomDraw (Additional2) but the result is the same, the rest of the aplication is not correctly refresh.

How can I draw out of the bounds of the node?

Thank you very much. I overrided the GetRepaintRect and now It 's working fine.
