--------the (lengthy) bottom line--------- so i ask, how can force an expose signal to a widget(drawingarea) that has never been exposed? ive tried various things they mention in documentation like invalidating a region or sending "expose_event" via g_signal_emit_by_name() which all fail. the closest ive come is by just calling the callback directly but it segfaults as the widget "window" has not been allocated memory(joy). im kind of stuck and ill take a clean or dirty answer about now. if you are thinking "redesign the app" please read the details as to why that isnt happening.
--------application details below----------- so here is a the deal, i have application that loads graphics from a file. the graphics are in a foriegn format and are decoded to a drawing area. the sum of the graphic contents is 64MB(32bit 4096x4096) which loads very quickly on linux. however, not so much on win32 due to being so large and win32 being slower. i have no problem with longer load times when loading the file but the problem is that the drawing area is not exposed until after you load the file. needless to say i would like to be able to load the image into the drawing area when loaded instead of when it is exposed as it make the app look slugish or frozen. i have checked the archive only to find solutions like "use a buffer and blit it" which isnt an option as that would double the data to 128MB which is far more than rediculous. -------------------------------- ok, so if you are that guy going "oh... that's easy" please share your ultimate wisdom of gtk+ with me. one more thing... figure it out or the kitten gets it!
