Declaration

type tcustomspacer = class(tscalingwidget)

Description

An invisible-by-default widget acting as a positional link between surrounding widgets: set linkleft/linktop/ linkright/linkbottom to some of the widgets around it, and moving or resizing the spacer repositions those linked widgets to keep the configured dist_* margins (see spaceroptionty for the exact rules).

Links widget positions through its link* properties, normally invisible; its own position follows the leading linked widget (linkleft/linktop) unless spao_glueright/ spao_gluebottom is set, in which case it instead follows the trailing one (linkright/linkbottom). With spao_glueright False: repositioning/resizing linkleft shifts the whole linked group; if an_right is set on linkright, the spacer instead resizes linkright (keeping its right margin), otherwise it shifts linkright (keeping its width). With spao_glueright True, the same holds symmetrically for linkright driving the group, and an_left on linkleft. spao_gluebottom works the same way vertically, with linktop/linkbottom and an_bottom/an_top. Compare with tsplitter, which is normally visible, can be user-dragged, and can save its position to a tstatfile; a tspacer is instead driven only by its linked widgets.
