    [CLOSED] Center desktop shortcuts on desktop

    Some customers can make you crazy :)

    I'm creating my shortcuts in codebehind like this:

     DesktopShortcut sc = new DesktopShortcut
                {
                    X = Conversie.ToString(xPosition),
                    Y = Conversie.ToString(yPosition),
                    ModuleID ="dmname",
                    Text = "shortcuttext",
                    IconCls = "iconclasss"
                 };
                MyDesktop.Shortcuts.Add(sc);
    Starting from the left top corner --> adding some pixels on x and y to place the different desktopshortcuts on the right place. Works like a charm.
    Suddenly a customer want to center these shortcuts. They need to be centered also after windowresize.

    Need some ideas... :)

    Hi,

    Unfortunately, there is no such functionality. So, you need to implement it manually.

    There is the .initShortcuts() function within the Desktop's sources.

    I can suggest you to override it as you wish directly into the Desktop's scripts.

    The following example will help you to start.

    This example is just to debug the .initShortcouts() function:

    1. Run the page under VS + IE
    2. Resize a browser window
    3. You are within the .initShortcuts() function

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.Net Example</title>

    <ext:ResourcePlaceHolder runat="server" Mode="ScriptFiles" />
    <script type="text/javascript">
        var myInitShortcuts = function () {
            var shortcuts = Ext.get('x-shortcuts');
            if (shortcuts) {
                debugger;
                this.col = { index: 1, x: 10 };
                this.row = { index: 1, y: 10 };
                var items = shortcuts.query('dt');
                for (var i = 0, len = items.length; i < len; i++) {
                    var item = Ext.Element.get(items[i]),
                        x = item.getAttributeNS('ext', 'X'),
                        y = item.getAttributeNS('ext', 'Y');

                    if (Ext.isEmpty(x) || Ext.isEmpty(y)) {
                        this.setPosition(item);
                    }
                    else {
                        x = eval(x.replace('{DX}', 'Ext.lib.Dom.getViewWidth()'));
                        y = eval(y.replace('{DY}', '(Ext.lib.Dom.getViewHeight() - taskbarEl.getHeight())'));
                        item.setXY([x, y]);
                    }
                }
            }
        };
    </script>
</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server" />
        <ext:Desktop ID="Desktop1" runat="server" BackgroundColor="black">
            <Modules>
                <ext:DesktopModule ModuleID="DesktopModule1" WindowID="DesktopWindow1" />
            </Modules>
            <Shortcuts>
                <ext:DesktopShortcut ModuleID="DesktopModule1" Text="Shortcut"  />
            </Shortcuts>
            <StartMenu>
                <Items>

                            <Click Handler="DesktopWindow1.show();" />
                        </Listeners>
                    </ext:MenuItem>
                </Items>
            </StartMenu>
            <Listeners>
                <Ready Handler="Ext.EventManager.removeResizeListener(this.desktop.initShortcuts, this.desktop);
                                Ext.EventManager.onWindowResize(myInitShortcuts, this.desktop);" />
            </Listeners>
        </ext:Desktop>
        <ext:DesktopWindow ID="DesktopWindow1" runat="server" Title="DesktopWindow" />
    </form>
