/** @page howto_window_page How to develop a window / dialog
|
|
*
|
|
* Windows and dialogs are related to each other. Dialogs are special kind of windows, but they behave
|
|
* slightly different. Dialogs stick on it's parent window, normal windows will be much more independant
|
|
* from it's parent window. Dialogs should be used to ask or note the user something, while windows should
|
|
* show data independantly from the main window.
|
|
* Dialogs are created by calling dlg_window_new() which in turn will call window_new().
|
|
* After that, dialogs can be developed the same way as windows, all window related functions in gui_utils.h
|
|
* can be used for both.
|
|
*
|
|
* @section window_create Create a window
|
|
*
|
|
* A typical window / dialog will be created by the following calls:
|
|
*
|
|
* - window_new() will create a new window with default position and size,
|
|
* use dlg_window_new() if you need a dialog (transient to the main window)
|
|
* - gtk_window_set_default_size() to set the default size of the window. Only
|
|
* needed, if the initial size is not appropriate, e.g. when a scrolled_window_new() is used.
|
|
* Be sure that the given size is larger than the initial size, otherwise the window might
|
|
* clip the content (at least on GTK1)
|
|
* - SIGNAL_CONNECT(my_win, "destroy", my_destroy_cb, NULL) callback, if some cleanup needs to be
|
|
* done after the window is destroyed, e.g. free up memory, or set the window pointer
|
|
* of a singleton window (only one instance allowed, e.g. about dialog) back to zero
|
|
* - create and fill in the content and button widgets
|
|
* - gtk_widget_show_all() shows all the widgets in the window
|
|
* - window_present() present the window on screen and
|
|
* (if available) set previously saved position and size
|
|
*
|
|
* @section window_events Events
|
|
*
|
|
* The following events are usually interesting:
|
|
*
|
|
* - "delete_event": the window managers "X" (e.g. upper right edge) of the window
|
|
* was clicked, default handler will call gtk_widget_destroy()
|
|
* - "destroy": everything is already gone, only cleanup of left over ressources
|
|
* can/should be done now
|
|
*
|
|
* @section window_hints Hints
|
|
*
|
|
* If you want to save size and position, be sure to call window_destroy() instead of only
|
|
* gtk_widget_destroy(), so you will probably have to SIGNAL_CONNECT to the "delete_event"!
|
|
*
|
|
* Don't use WIDGET_SET_SIZE() to set the size of a window,
|
|
* use gtk_window_set_default_size() for that purpose!
|
|
*
|
|
* Be sure to call window_present() / window_destroy() appropriately, if you
|
|
* want to have size and position of the window handled by ui_util.
|
