Description
The splitContainer widget connects to 'onmousemove' and 'onmouseup' events in "beginSizing" method. These need to be disconnected in "endSizing" method.
Else on every resize- the number of times "changeSizing" and "endSizing" are called will increase, with the number of times you resize !
Worse still, any clicks in the widget will also call these functions as many times as the widget has been resized(coz of the mouse up connect)
This is very expensive if you have a lot widgets in the split content panes and you connect to the "endSizing", to resize all these widgets
Here is a test that will show the bug... Please place the following code in a html file and place the file in dojo-release-0.9.0dijit estslayout
code: <!DOCTYPE HTML PUBLIC "-W3CDTD HTML 4.01EN"
<html> <head>
<title>SplitContainer? Widget Demo</title>
<script type="text/javascript" src="../testBidi.js"></script> <script> function attachResize() {
var splitContObj = dijit.byId('mySplitContainer'); dojo.connect(splitContObj,"endSizing","resize")
} function resize() {
alert("endSizing called!");
} </script> <script type="text/javascript" src="../../../dojo/dojo.js"
djConfig="isDebug: true, parseOnLoad: true"></script>
<script type="text/javascript">
dojo.require("dijit.layout.SplitContainer?"); dojo.require("dijit.layout.ContentPane?"); dojo.require("dojo.parser"); scan page for widgets and instantiate them dojo.addOnLoad(attachResize)
</script> <style type="text/css">
@import "../../../dojo/resources/dojo.css"; @import "../../themes/tundra/tundra.css"; @import "../css/dijitTests.css"; .dojoContentPane {
padding:1em;
}
</style>
</head> <body class="tundra">
<h1 class="testTitle"> Dijit Split Container Test<br/> Resize the panes once and then click on any of the two boxes!<br/> Now resize again and click again.<br/> And again......<br/> The number of times "endsizing" is called increases propotionally with the number of times you resize!
