If it is Truethen the scrollbar will only appear when it is needed,unless forceBars is True.When True the scrollbars that have been allowed willalways be visible on the screen. If False the scrollbarswill be visible only when the inner window islarger than the frame.These callbacks will be executed whenever the Viewportadjusts the viewed area of the child. Thecall_data parameter is a pointer to an XawPannerReportstructure.useBottomuseRightBy default the scrollbars appear on the left and top ofthe screen. These resources allow the vertical scrollbarto be placed on the right edge of the Viewport,and the horizontal scrollbar on the bottom edge ofthe Viewport.125
Composite and ConstraintWidgetsLayout SemanticsThe Viewport widget manages a single child widget. When the size of the child islarger than the size of the Viewport, the user can interactively move the child withinthe Viewport by repositioning the scrollbars.The default size of the Viewport before it is realized is the width and/or height of thechild. After it is realized, the Viewport will allow its child to grow vertically or horizontallyif allowVert or allowHoriz are set, respectively. If the corresponding verticalor horizontal scrollbar is not enabled, the Viewport will propagate the geometryrequest to its own parent and the child will be allowed to change size only ifthe Viewport's parent allows it. Regardless of whether or not scrollbars are enabledin the corresponding direction, if the child requests a new size smaller than theViewport size, the change will be allowed only if the parent of the Viewport allowsthe Viewport to shrink to the appropriate dimension.The scrollbar children of the Viewport are named horizontal and vertical. By usingthese names the programmer can specify resources for the individual scrollbars.XtSetValues can be used to modify the resources dynamically once the widget IDhas been obtained with XtNameToWidget.NoteAlthough the Viewport is a Subclass of the Form, no resources for the Formmay be supplied for any of the children of the Viewport. These constraintsare managed internally and are not meant for public consumption.126
