Hi I have a customer that is running VMS 5.2 & ADA 1.5 . He is defining a DialogBox and a ListBox widgets in a UIL. Both are defined with width arguments. The ListBox is a CONTROL of the DialogBox. When running the Application, (and doing MANAGE the heirarchy) he gets (from time to time) the following message: the message:X-ERROR event recieved from server: BadDrawable parameter not a pixmap or window, Failed requet. major opcode 62 x_copyarea Failed request minor opcode 0 (If applicable) When he cancels the width arguments in the UIL file, he does not get the above message. Any Hints? *-Doron-*

This is a sort of wild guess based on an old bug. It used to me that some subwidgets of a larger widget would calculate their width by subtracting a constant from the width of their parent. If you started out the parent widgets with a very small width, expecting to resize it later, then the subwidget would try to create a window with a negative width. Since width is unsigned, it turned out huge and the server blew up. We changed the server to check for that case and reject it. This, however, means that the subwidget window is not created, and thus the window id the toolkit gets from CreateWindow is invalid. If this is still happening, that might explain the BadDrawable message. Try making the default UIL width bigger. Burns | |||||
