Hi Rooters, This is a bug report. I have a GUI with a TROOTEmbeddedCanvas inside. When a histogram is displayed and I decrease the size of the dialog, I get serveral errors when the canvas size gets zero: Error in <TGX11TTF::DrawText>: error getting background image Error in <TGX11TTF::DrawText>: error getting background image Error in <TGX11TTF::DrawText>: error getting background image Error in <RootX11ErrorHandler>: BadValue (integer parameter out of range for operation) (XID: 0) or: Error in <TGX11TTF::DrawText>: error getting background image Error in <TGX11TTF::DrawText>: error getting background image Error in <TGX11TTF::DrawText>: error getting background image Error in <TGX11TTF::DrawText>: error getting background image Error in <RootX11ErrorHandler>: BadMatch (invalid parameter attributes) (XID: 0) This error can be simply reproduced using the guitest-example: In Test->Dialog->Tab 3 push the "Start filling Hists" button and then decrease the size of the window until the histogramms disappear. Then guitest crashes with the above errors and uses 99.9% CPU... Andreas ROOT: 3.01.06 (from cvs, 28.
