The GIMP Help System part 1: Press "F1" in any dialog to pop up
the help page for this dialog.
Moved the widget constructors from preferences_dialog.[ch] and the
query boxes from interface.[ch] to gimpui.[ch].
The dialog constructors take a help_func and a help_data
parameter and install the "F1" accelerator which emits the new
"help" signal.
The "help" signal callback calls help_func(help_data) which finally
has to call gimp_help() which in turn invokes the help browser.
Still have to find a proper way to (1) prevent "F1" being assigned
to some menu item and (2) to catch "F1" while browsing the menu
trees in order to pop up the help for the selected item.
* app/menus.c: a <Toolbox>/File/Help... menu item.
* app/commands.[ch]: a command callback for the "Help..." menu item.
* app/gimprc.[ch]: new boolean gimprc variable "use_help".
* app/info_dialog.[ch]: pass a help function and data to the info
dialog constructor.
* app/tools.[ch]: store the tools help page names in the tool info
structure. Export a special tools_help_func() which shows the help
page for the active tool.
* app/[all files calling a dialog constructor]: pass the dialog's
help page to the constructor.
Most dialogs are now created by gimp_dialog_new() which also sets
up the action_area and the WM delete event callback, so I removed
the resp. code from these files.
Fixed some minor bugs and did some other stuff but didn't change
any logic except dialog creation.
* plug-ins/helpbrowser/helpbrowser.c: don't try to call a running
help browser and don't install any menu path (all done in
app/gimphelp.[ch] now).
