Re: Combobox disable item

Hi Mike, What part of the combo box are you trying to disable? If you want to filter rows or columns you can set up a tree model filter to do so. Maybe something like the following? Eric /* gcc -Wall combo_filter1.c -o combo_filter1 `pkg-config --cflags --libs gtk+-3.0` Tested

Re: Combobox focus event

Another thing to give a try is just to set a boolean in the "set-focus-child" callback. Not sure if this will always work. I think that it should. I don't know the best workaround for the "focus-in-event" in a combo box. It isn't obvious how to connect that signal for the combobox. Eric

Re: Combobox focus event

Thomas, Your original question looked easy. Connect the "focus-in-event" to the combo box and everything will work fine. The "focus-in-event" works with other widgets. So I tried it out. Couldn't get it to work. Tried changing some combo box functions around and still couldn't get it to work.

Hi Thomas, You can try getting the private toggle button in the combo box. This isn't a solution using the given GTK api but if you want to inspect the how to get the "focus-in-event" to work with a combo box, this might be helpful. You are working in C right? Eric /* gcc -Wall
