Accelerators - managing accelerator tables
#include <X11/Intrinsic.h>
XtAccelerators XtParseAcceleratorTable(const char * source);
void XtInstallAccelerators(Widget destination, Widget source);
void XtInstallAllAccelerators(Widget destination, Widget source);
source Specifies the accelerator table to compile.
destination
Specifies the widget on which the accelerators are to be
installed.
source Specifies the widget or the root widget of the widget tree
from which the accelerators are to come.
The XtParseAcceleratorTable function compiles the accelerator table
into the opaque internal representation.
The XtInstallAccelerators function installs the accelerators from
source onto destination by augmenting the destination translations with
the source accelerators. If the source display_accelerator method is
non-NULL, XtInstallAccelerators calls it with the source widget and a
string representation of the accelerator table, which indicates that
its accelerators have been installed and that it should display them
appropriately. The string representation of the accelerator table is
its canonical translation table representation.
The XtInstallAllAccelerators function recursively descends the widget
tree rooted at source and installs the accelerators of each widget
encountered onto destination. A common use os to call XtInstallAll-
Accelerators and pass the application main window as the source.
