I would like to automatically resize a window to its
content. I was thinking of using an outer table to
detect the size of my content, then use window.resizeTo( ).
The problem is I'm not sure how I can determine the size
of what I think is referred to as the 'chrome' - the
window borders, toolbars, etc.
Is there a way to determine the height and width of the
chrome so that I can supply the correct parameters to the
resizeTo method?
The dimension of the top and left chrome can be determined on browsers
that expose the screen offsets of their window to scripting, given a
mouse input event. By reading the mouse's screen co-ordinates, and its
viewport co-ordinates and using the difference to give the screen
co-ordinates of the viewport. The difference between the screen
co-ordinates of the window and the screen co-ordinates of the viewport
give the dimensions of the chrome at the top of the window and the
chrome to the left.
The screen co-ordinates of the window are not universally available in
browser object models (and in framesets the values don't necessarily
have the same meaning).
The other proposed possible strategy for determining the chrome
dimensions in total is to measure the viewport dimensions, re-size the
window to the original viewport dimensions and then re-measure the
viewport dimensions. The difference being the total dimensions of the
chrome (left+right and top+bottom), assuming that the second set of
viewport dimensions didn't drop to zero, which would invalidate the
results.
Obviously re-sizing the window a couple of times is not going to look
that good to the user. And these days the ability to re-size a browser
window is subject to user veto, so it will often not work at all.
A better approach is probably to adopt a fluid HTML design that adapts
to whatever size the user's window happens to be.
