Determines whether a window is currently collapsed.

Boolean IsWindowCollapsed (
    WindowRef window
);

window

A pointer to the window to be examined.

function result

If true, the window is collapsed. If false, the window is expanded.

DISCUSSION

Only window definition functions that return the feature bit kWindowCanCollapse in response to a kWindowGetFeatures message support this function; see GetWindowFeatures. Your window definition function should call IsWindowCollapsed to determine whether or not a window is collapsed, so you can modify its structure and content regions as appropriate. Typically, a window’s content region is empty in a collapsed state.

VERSION NOTES

This function is available with Appearance Manager 1.0 and later.

AVAILABILITY
