Children of GenView objects always appear at a specified edge of the view; you may decide which children appear on the top, left, right, or bottom, but all children must appear along one of the view's edges. Additionally, you may request that the children be placed next to the view's scrollers; for example, if you wanted a page number to appear at the foot of the view, you might define a GenGlyph that seeks the horizontal scroller.
Each child's placement is determined independently of the others. Each child, therefore, must have a hint that describes where in relation to the view it would like to appear. If the requested configuration is supported by the specific UI, the object will appear where requested. If the specific UI does not support the desired configuration, the child will likely appear below the view. The view may have more than one child. If no hint of location is given for any child, that child will appear with the horizontal scroller.
The location hints (defined by
GenClass
) available to a GenView's children include
HINT_SEEK_X_SCROLLER_AREA
The object should be placed with the horizontal scroller object.
HINT_SEEK_Y_SCROLLER_AREA
The object should be placed with the vertical scroller object.
HINT_SEEK_LEFT_OF_VIEW
The object should be forced to the left side of the view.
HINT_SEEK_RIGHT_OF_VIEW
The object should be forced to the right side of the view.
HINT_SEEK_TOP_OF_VIEW
The object should be forced to the top edge of the view.
HINT_SEEK_BOTTOM_OF_VIEW
The object should be forced to the bottom edge of the view.You may also specify your own scroller objects anywhere below the view in the generic object tree. This is described in the section on Scrolling, below.
