Subject: proposed contextmenu API
To: Elliot Winard <[EMAIL PROTECTED]>
Here's a more fleshed out example of the API I am working on. There are two
independent ways to get the callback when someone clicks on an item.
You can pass a delegate that will get executed, or you can listen for a "onselectitem"
event from an LzContextMenuItem.
The LzContextMenu itself sends a "onselect" event just when the user right clicks, so you have a little time to dynamically rearrange the menu before it displays.
<canvas width="100%" height="80%" >
<debug fontsize="12"/>
<simplelayout/>
<view width="100" height="100" bgcolor="#cccccc" name="v1">
<method event="oninit">
var cm = new LzContextMenu();
var item1 = cm.makeMenuItem('Item1', new LzDelegate(this, "handlerightclick"));
cm.addItem(item1);
var item2 = cm.makeMenuItem('Item2', new LzDelegate(this, "handlerightclick"));
cm.addItem(item2);
var item3 = cm.makeMenuItem('Item3', new LzDelegate(this, "handlerightclick"));
item3.setEnabled(false);
cm.addItem(item3);
var item4 = cm.makeMenuItem('Item4', new LzDelegate(this, "handlerightclick"));
item4.setSeparatorBefore(true);
cm.addItem(item4);
var item5 = cm.makeMenuItem('Show Dialog', new LzDelegate(this, "handlerightclick"));
cm.addItem(item5);
// Menu items generate a "onselectitem" when they are selected
new LzDelegate(this, "showdialog", item5, "onselectitem");
this.setContextMenu(cm);
// "onselect" event is sent as soon as the menu gets a mousedown on the right button.
// This gives you a chance to (quickly) rearrange the menu on the fly.
new LzDelegate(this, "menuselected", cm, "onselect");
// "onselectitem" event is sent when an item is selected from the menu
new LzDelegate(this, "menuitemselected", item1, "onselectitem");
Debug.write(cm);
</method>
<method name="menuselected" args="val">
Debug.write("A right click on the menu was detected, val= ", val);
</method>
<method name="menuitemselected" args="val">
Debug.write("A right click on an item was detected, val= ", val);
</method>
<method name="handlerightclick" args="val">
Debug.write("handle item handlerightclick, val=", val);
</method>
<method name="showdialog">
md.open();
</method>
</view>
<modaldialog id="md" width="200" height="200">
<simplelayout/>
<text>This is your dialog</text>
<button isdefault="true">OK</button>
</modaldialog>
</canvas>
