Hi,
I'm trying to customize qx.ui.menu.Button. I need one extra
qx.ui.basic.Label called "price" between Button/label and Button/shortcut.
And I get this error: Assertion error! Wrong 'left' argument. The layout of
the widgetqx.ui.menu.Menu[204-0] returned an invalid size hint!: Expected
value to be an integer but found NaN!.
My code is:
qx.Class.define("my.ui.MenuButtonWithPrice",
{
extend : qx.ui.menu.Button,
construct : function(label, icon, command, price)
{
this.base(arguments, label, icon, command);
if (price != null) {
this.setPrice(price);
}
},
properties :
{
price :
{
check : "String",
apply : "_applyPrice",
nullable : true,
event: "changePrice"
}
},
members :
{
_createChildControlImpl : function(id, hash)
{
var control;
switch(id)
{
case "price":
control = new qx.ui.basic.Label;
control.setAnonymous(true);
this._add(control, {column:2});
break;
case "shortcut":
control = new qx.ui.basic.Label;
control.setAnonymous(true);
if (!this.getShowCommandLabel()) {
control.exclude();
}
this._add(control, {column:3});
break;
case "arrow":
control = new qx.ui.basic.Image;
control.setAnonymous(true);
this._add(control, {column:4});
break;
}
return control || this.base(arguments, id);
},
getChildrenSizes : function()
{
var priceWidth = 0;
var sizes = this.base(arguments);
if (this._isChildControlVisible("price"))
{
var price = this.getChildControl("price");
priceWidth = price.getMarginLeft() + price.getSizeHint().width +
price.getMarginRight();
}
sizes.splice(2, 0, priceWidth);
return sizes;
},
_applyPrice : function(value, old)
{
if (value) {
this._showChildControl("price").setValue(value);
} else {
this._excludeChildControl("price");
}
}
}
});
