LessTif Internal Functions

Introduction

Below is a list of functions currently taken from the LessTif header files.

If you know the functionality of a particular function why not write a few lines explaining what it does.

void _XmCalcLabelDimensions(Widget w);

Unknown Function

Boolean _XmGetInDragMode(Widget w);

returns True, if the widget (e.g. push button,...) resides in a menu and the user is currently dragging the mouse with button 1 pressed over the menu items. This way a widget can figure out, whether it must redraw itself in the armed state if the widget gets a PrimitiveEnter action.

Unknown Function

void _XmInternAtomAndName(Display *display, Atom atom, String name);=

Associates an atom name with an atom id (and vice versa) without the need to query the X server first for the atom id. This way any name to id mapping (as well as the id to name mapping) can be set on a given display.

void _XmVirtualToActualKeysym(Display *Dsp, KeySym VirtualKeysym, KeySym *RealKeysymReturn, Modifiers *ModifierReturn);

For the given virtual keysym (which must be one of the = osfXK_xxx keysyms) returns the real keysym as well as the modifiers which make up that particular virtual keysym. If asked for an invalid virtual keysym, _XmVirtualToActualKeysym returns NoSymbol for the real keysym.

int _XmVirtKeysLoadFallbackBindings(Display *Dsp, String *Bindings);=

Installs the default key bindings for a specific display. If th= ere are any vendor specific default bindings available, then the appropiate one= will be installed instead of the fallback key bindings. Additionally, the bindings installed are returned in Bindings. The caller is responsible for freeing the space occupied by this key binding description string. The return code seems to be always zero. At least LessTif will always retur= n a zero...

Boolean _XmVirtKeysLoadFileBindings(String filename, String *binding= );

Reads in a file containing a description of the virtual key bindings. If succesful, returns True and the description string. The caller= is responsible for freeing the memory lateron.

void _XmVirtKeysInitialize(Widget w);

Sets up the virtual key bindings for a display. The widget specified must be a XmDisplay widget, otherwise _XmVirtKeysInitialize will deny the attempt to set up the key bindings. The function first checks several places in order to catch up key binding description. If all fails, it will install fallback key bindings. This internal function is called during when initializing a XmDisplay widget.

void _XmVirtKeysDestroy(Widget w);

Cleanup any leftovers from the virtual binding mechanism when destroying a XmDisplay widget.

void _XmVirtKeysHandler(Widget w, XtPointer Data, XEvent *Event, Boolean *ContDispatch);

This handler is installed on every widget. It just records the current key press event in an widget instance field private to a XmDisplay widget.
