+# onResize
+`onResize(self)`<br>
+This is a custom event which gets triggered as soon as the parent frame gets resized.
+
+Here is a example on how to add a onResize event to your button:
+
+```lua
+local basalt = require("basalt")
+
+local main = basalt.createFrame()
+local aButton = main:addButton():setPosition(3,3)
+
+local function onButtonResize(self)
+    local width = main:getWidth()
+    self:setSize(width, 3)
+end
+
+aButton:onResize(onButtonResize)
+```
