PANEL:TestHover
Description
Called to test if the panel is being hovered by the mouse. This will only be called if the panel's parent is being hovered.
Arguments
Returns
1 boolean
Return false when the cursor is not considered on the panel, true if it is considered on the panel. Do not return anything for default behavior.
Example
Makes the button detect clicks as if the button was circular - not rectangular.
concommand.Add( "testvgui1", function()
local frame = vgui.Create( "DFrame" )
frame:SetSize( 300, 400 )
frame:Center()
frame:MakePopup()
local DermaButton = vgui.Create( "DButton", frame )
DermaButton:SetText( "Say hi" )
DermaButton:SetPos( 25, 50 )
DermaButton:SetSize( 250, 250 )
function DermaButton:DoClick( self ) chat.AddText( "Hello world" ) end
function DermaButton:TestHover( x, y )
local x, y = self:ScreenToLocal( x, y ) -- Convert to local coordinates
local dist = math.sqrt( (x - self:GetWide() / 2) ^ 2 + ( y - self:GetTall() / 2 ) ^ 2 ) -- Simple distance calculation
return dist < math.min( self:GetWide(), self:GetTall() ) / 2 -- Return true if the cursor is within the buttons circular radius
end
function DermaButton:Paint( w, h )
-- Original size
draw.RoundedBox( 0, 0, 0, w, h, Color( 255, 255, 255, 128 ) )
-- Circular visualization
local size = math.min( w, h ) / 2
surface.DrawCircle( w / 2, h / 2, size, Color( 255, 120, 0 ) )
end
end )
