ControlHintTooltip Property

Changes the tooltip text. The tooltip appears when the user's mouse cursor stays idle over this control for a few moments, provided that the MouseFilter property is not . You can change the time required for the tooltip to appear with gui/timers/tooltip_delay_sec option in Project Settings.

The tooltip popup will use either a default implementation, or a custom one that you can provide by overriding _MakeCustomTooltip(String). The default tooltip includes a PopupPanel and Label whose theme properties can be customized using Theme methods with the "TooltipPanel" and "TooltipLabel" respectively. For example:

var style_box = StyleBoxFlat.new()
style_box.set_bg_color(Color(1, 1, 0))
style_box.set_border_width_all(2)
# We assume here that the `theme` property has been assigned a custom Theme beforehand.
theme.set_stylebox("panel", "TooltipPanel", style_box)
theme.set_color("font_color", "TooltipLabel", Color(0, 1, 1))
