Now I am trying to create this window in C++ using gtkmm.[snip] If you have to create ten windows like the one depicted in your original post, it appears that you'd have 320 combo boxes. In order to avoid having that many combo box objects, I would just create the 32 that will be in view at any one time and use radio buttons to change the port and single/multiple bit modes. Then I'd store the values that would populate the data contained by the ComboBoxText objects in an array of std::vectors for each possible mode and just repopulate the combo boxes when a particular mode is selected via the radio button array. I hope this provides food for thought. Bob Caryl |
