I am sending this for a friend of mine, who doesn't have access to the net. Please reply with email, so I can forward the responses to my friend. Margot margot@spex.nl UNWANTED EXPOSE EVENTS FROM ATTACHEDDIALOGBOX-PARENT I would like to ask if anybody has encountered a problem with the "attached dialog box" widget from the DECWindows toolkit concerning unwanted expose events. I have designed a simple widget (directly inherited from core) wich i hang under an adb-widget. Every time the application makes a change in the resources of the simple widget, an (undesired) expose event is generated. The set_values method of the simple widget seems to be innocent. Even if I set the set_values method reference to NULL there are still expose events generated. The occurs only when using an adb-widget as a parent, using a main window widget or hanging the simple sidget directly under the top level shell seems to work fine. Possible the adb-widget set_values method is resposible, it is called automatically since the adb-widget inherits from constraint. But I can't imagine why they would have designed it like that since no constraint resources are modified and any redrawing is uncalled for. Since I don't have DECWindows widget source code I can't check my suspicions. Does anyone know more ? Daan Broeder.
