XtCreateWindow(3Xt) XT FUNCTIONS XtCreateWindow(3Xt)NAME
XtCreateWindow - window creation convenience function
SYNTAX
void XtCreateWindow(Widget w, unsigned int window_class, Visual *visual, XtValueMask value_mask, XSetWindowAttributes *attributes);
ARGUMENTS
attributes
Specifies the window attributes to use in the XCreateWindow call.
value_mask
Specifies which attribute fields to use.
visual Specifies the visual type (usually CopyFromParent).
w Specifies the widget that is used to set the x,y coordinates and so on.
window_class
Specifies the Xlib window class (for example, InputOutput, InputOnly, or CopyFromParent).
DESCRIPTION
The XtCreateWindow function calls the Xlib XCreateWindow function with values from the widget structure and the passed parameters. Then,
it assigns the created window to the widget's window field.
XtCreateWindow evaluates the following fields of the Core widget structure:
o depth
o screen
o parent -> core.window
o x
o y
o width
o height
o border_width

XtConfigureWidget(3Xt) XT FUNCTIONS XtConfigureWidget(3Xt)NAME
XtConfigureWidget, XtMoveWidget, XtResizeWidget - move and resize widgets
SYNTAX
void XtConfigureWidget(Widget w, Position x, Position y, Dimension width, Dimension height, Dimension border_width);
void XtMoveWidget(Widget w, Position x, Position y);
void XtResizeWidget(Widget w, Dimension width, Dimension height, Dimension border_width);
void XtResizeWindow(Widget w);
ARGUMENTS
width
height
border_width
Specify the new widget size.
w Specifies the widget.
x
y Specify the new widget x and y coordinates.
DESCRIPTION
The XtConfigureWidget function returns immediately if the specified geometry fields are the same as the old values. Otherwise,
XtConfigureWidget writes the new x, y, width, height, and border_width values into the widget and, if the widget is realized, makes an Xlib
XConfigureWindow call on the widget's window.
If either the new width or height is different from its old value, XtConfigureWidget calls the widget's resize procedure to notify it of
the size change; otherwise, it simply returns.
The XtMoveWidget function returns immediately if the specified geometry fields are the same as the old values. Otherwise, XtMoveWidget
writes the new x and y values into the widget and, if the widget is realized, issues an Xlib XMoveWindow call on the widget's window.
The XtResizeWidget function returns immediately if the specified geometry fields are the same as the old values. Otherwise, XtResizeWidget
writes the new width, height, and border_width values into the widget and, if the widget is realized, issues an XConfigureWindow call on
the widget's window.
If the new width or height are different from the old values, XtResizeWidget calls the widget's resize procedure to notify it of the size
change.
The XtResizeWindow function calls the XConfigureWindow Xlib function to make the window of the specified widget match its width, height,
and border width. This request is done unconditionally because there is no way to tell if these values match the current values. Note
that the widget's resize procedure is not called.
There are very few times to use XtResizeWindow; instead, you should use XtResizeWidget.
