stacked-tree-increase-font-height
Decrease or increase the font size in a stacked-tree.
The functions stacked-tree-increase-font-height
and stacked-tree-decrease-font-height
try to increase/decrease the point size of the font in
stacked-tree
. They add/subtract 1 from the size of the current font, and try to find a font with the new size. If this does not work, they add/subtract 2 and try again. If they find a new font, they set the font in
stacked-tree
to the new font. The heights of the rectangles are adjusted to fit the new font height.
stacked-tree-increase-font-height
and stacked-tree-decrease-font-height
are used by the Ctrl->
and Ctrl-<
gestures and you can use them to implement your gestures. The &rest
ignore
means that you can use these functions in the input-model directly.
