Starts or stops resizing a window with the mouse.<br />
<br />
<pre><br />
WindowSetResizing(windowName, resizing, point, keepAspectRatio)<br />
</pre><br />
<br />
== Arguments ==<br />
;windowName : <code>string</code> – Name of the window.<br />
;resizing : <code>boolean</code> – <code>true</code> to start resizing, <code>false</code> to stop.<br />
;point : <code>string</code> – The edge or corner the resize works on: <code>"topleft"</code>, <code>"topright"</code>, <code>"bottomleft"</code>, <code>"bottomright"</code>, <code>"top"</code>, <code>"bottom"</code>, <code>"left"</code> or <code>"right"</code>. Ignored when <code>resizing</code> is <code>false</code>.<br />
;keepAspectRatio : <code>boolean</code> – <code>true</code> to keep the window's width-to-height ratio while resizing.<br />
<br />
== Returns ==<br />
Nothing.<br />
<br />
== Details ==<br />
* <code>keepAspectRatio</code> is stored on every call, also when <code>resizing</code> is <code>false</code>.<br />
* With <code>resizing = true</code>, the client records the current mouse position and starts the resize from <code>point</code>.<br />
* <code>"center"</code> and unknown names do not start a resize; [[API:WindowGetResizing|WindowGetResizing]] then returns <code>false</code>.<br />
* With <code>resizing = false</code>, any running resize ends. The stock UI passes <code>""</code> as <code>point</code> in that case.<br />
* Both flags must be real booleans. Passing <code>nil</code> or a number raises an ''Invalid Parameters'' error.<br />
<br />
== Errors ==<br />
* <code>Error in function call 'WindowSetResizing': Window %s does not exist</code><br />
* <code>Error in function call 'WindowSetResizing': Window %s is currently locked and may not be modified from lua. ...</code><br/>This check never triggers in the current client. See [[API:WindowSetShowing|WindowSetShowing]].<br />
<br />
== Example ==<br />
Starting a resize in <code>WindowUtils.BeginResize</code>, from <code>easystem_windowutils/source/windowutils.lua</code>:<br />
<pre><br />
WindowAddAnchor( "ResizingWindowFrame", anchorCorner, windowName, anchorCorner, 0, 0 )<br />
<br />
WindowSetResizing( "ResizingWindowFrame", true, anchorCorner, false );<br />
WindowSetShowing( "ResizingWindowFrame", true )<br />
</pre><br />
<br />
Ending it in <code>WindowUtils.EndResize</code>, same file:<br />
<pre><br />
WindowSetResizing( "ResizingWindowFrame", false, "", false );<br />
</pre><br />
