<function name="SetBGColor" parent="Panel" type="classfunc"> <file line="32-L40">lua/includes/extensions/client/panel.lua</file> <description> Sets the background color of a panel such as a <page>RichText</page>, <page>Label</page> or <page>DColorCube</page>. Sets the background color of a panel such as a <page>RichText</page>, <page>Label</page>, <page>DColorCube</page> or the base <page>Panel</page>. ⤶ For many panels, such as <page>DLabel</page> and <page>Panel</page>, you must use <page>Panel:SetPaintBackgroundEnabled</page>( true ) for the background to appear.⤶ ⤶ Please note that for most panels the engine will overwrite the foreground and background colors a frame after panel creation via the <page>PANEL:ApplySchemeSettings</page> hook, so you may want to set the color in that hook instead.⤶ ⤶ See <page>Panel:SetFGColor</page> for the foreground color.⤶ <note>This doesn't apply to all VGUI elements and its function varies between them</note> ⤶ For <page>DLabel</page> elements, you must use <page>Panel:SetPaintBackgroundEnabled</page>( true ) before applying the color.⤶ ⤶ This will not work on setup of the panel - you should use this function in a hook like <page>PANEL:ApplySchemeSettings</page> or <page>PANEL:PerformLayout</page>.⤶ </description> <realm>Client and Menu</realm> <args> <arg name="r or color" type="number">The red channel of the color, or a <page>Color</page>.
