Question

How do I get the height of a GWT object in pixels? I am trying to find a getHeight method or something similar..

Answer 1

You are probably looking for getOffsetHeight() (inherited by every part of the UI from UiObject):

Gets the object’s offset height in
pixels. This is the total height of
the object, including decorations such
as border, margin, and padding.

There’s also the getClientHeight() from Element:

Returns the inner height of an element
in pixels, including padding but not
the horizontal scrollbar height,
border, or margin.

You can access the underlying Element of every UiObject (meaning Widgets, etc) via the getElement() method.

Be sure to check that the item is visible at the time the size is read, else you will get 0.
