Detailed Description

Calculating and drawing of bounding boxes for "button sections". That is, each group of buttons separated by a separator spacer button.

Function Documentation

button_section_bounds_calc()

static Vector< rcti > button_section_bounds_calc ( const ARegion * region, const bool add_padding )

static

Calculate a bounding box for each section. Sections will be merged if they are closer than UI_BUTTON_SECTION_MERGE_DISTANCE.

If a section is closer than UI_BUTTON_SECTION_MERGE_DISTANCE to a region edge, it will be extended to the edge.

Returns

the bounding boxes in region space.

UI_region_button_sections_draw()

void UI_region_button_sections_draw	(	const ARegion *	region,
		int	colorid,
		uiButtonSectionsAlign	align )

Draw a background with rounded corners behind each visual group of buttons. The visual groups are separated by spacer buttons (uiItemSpacer()). Button groups that are closer than UI_BUTTON_SECTION_MERGE_DISTANCE will be merged into one visual section. If the group is closer than that to a region edge, it will also be extended to that, and the rounded corners will be removed on that edge.

Note

This currently only works well for horizontal, header like regions.
