Package glfw provides a full Fyne desktop driver that uses the system OpenGL libraries.

AbsolutePositionForObject returns the absolute position of an object in a set of object trees.

FindObjectAtPositionMatching is used to find an object in a canvas at the specified position.

ReverseWalkVisibleObjectTree will walk an object tree in reverse order for all visible objects executing the passed functions following the following rules: - beforeChildren is called for the start obj before traversing its children - the obj's children are traversed by calling walkObjects on each of the visible items - afterChildren is called for the obj after traversing the obj's children The walk can be aborted by returning true in one of the functions: - if beforeChildren returns true, further traversing is stopped immediately, the after function will not be called for the obj where the walk stopped, however, it will be called for all its parents.

WalkCompleteObjectTree will walk an object tree for all objects (ignoring visible state) executing the passed functions following the following rules: - beforeChildren is called for the start obj before traversing its children - the obj's children are traversed by calling walkObjects on each of the items - afterChildren is called for the obj after traversing the obj's children The walk can be aborted by returning true in one of the functions: - if beforeChildren returns true, further traversing is stopped immediately, the after function will not be called for the obj where the walk stopped, however, it will be called for all its parents.

WalkVisibleObjectTree will walk an object tree for all visible objects executing the passed functions following the following rules: - beforeChildren is called for the start obj before traversing its children - the obj's children are traversed by calling walkObjects on each of the visible items - afterChildren is called for the obj after traversing the obj's children The walk can be aborted by returning true in one of the functions: - if beforeChildren returns true, further traversing is stopped immediately, the after function will not be called for the obj where the walk stopped, however, it will be called for all its parents.

WithContext allows drivers to execute within another context.
