Dear Rooters Since I want to write a new gui, I am testing the tutorial example guitest.C. When running guitest.C on MacOS X using root 3.05/02 from 31 January 2003 I get the following output: ---------------- root [0] .x guitest.C TestMainFrame has been created. Welcome! root [1] Error in <RootX11ErrorHandler>: BadWindow (invalid Window parameter) (XID: 20972049, XREQ: 61) menu popped up menu popped down fIniDir = . (dir: .) menu popped up // etc.... DoButton: id = 101 Tab item 4 activated Tab item 3 activated Terminating dialog: OK pressed *** Break *** illegal instruction Root > Error in <RootX11ErrorHandler>: BadDrawable (invalid Pixmap or Window parameter) (XID: 20972530, XREQ: 74) ----------------- When testing my own old gui, which I have written more than one year ago, I realized that when I open a dialogbox very often, I get finally a *** Break *** bus error. I did not get this behavior before. The same happens when I open "Dialog.." in guitest.C a couple of times. Furthermore, adding and removing a Tab in this dialog a couple of times also causes a *** Break *** bus error. Furthermore, there is a problem with Color Selector: Although I can add the first custom color, it is not possible to add a second custom color. Could it be that in the new root version(s) the GUI classes are less stable than in earlier versions of root? Personally, I think it is important that the GUI classes of root become as stable as the other root classes are. I hope that my observations help to debug the GUI classes.
