Detailed Description

Function Documentation

isChildOf()

zfbool ZFUIViewUtil::isChildOf ( ZFUIView * view, ZFUIView * parentToCheck )

extern

check whether this view is child of specified view (recursively)

true if view equals to this view

viewAtPos()

zfanyT< ZFUIView > ZFUIViewUtil::viewAtPos ( ZFUIView * view, const ZFUIPoint & pos, zfbool filterDisabledView = (_ZFT_t_zffalse), zfbool filterInternalView = (_ZFT_t_zftrue) )

extern

recursively check child at position (relative to the view)

may be invalid if layout step not finished

viewRectToParentT()

void ZFUIViewUtil::viewRectToParentT ( ZFUIRect & rect, ZFUIView * view, ZFUIView * parent = (zft_zfnull) )

extern

check rect of view relative to parent, return ZFUIRectZero if not child of parent or invalid

result value would be invalid until whole layout step finished
unlike ZFUIViewPositionOnScreen, this method does not depends on impl, however, result may be invalid if view's parent contains ZFUINativeViewWrapper
this method would calculate rect depends on ZFUIView::layoutChildOffset recursively
