Hi all,
I want to remove both children of a split pane by using the pane's
remove-method like this:
if (this.getChildren().length == 2) {
this.remove(this.getChildren()[0]);
this.remove(this.getChildren()[0]);
}
This code is inside a class that inherits from qx.ui.splitpane.Pane so the
"this" keyword refers to the split pane.
However, I get the following error:
Remove Error: dummy.ui.view.View[147] is not a child of this widget!
The exception is thrown on the second remove. The first
this.getChildren()[0] statement returns the dummy.ui.view.View[111] object
which can be removed successfully. The second one correctly returns a
dummy.ui.view.View[147] object which is, according to the strange error
message, not a child, although its returned by the getChildren() method. How
is this possible?
Thx
Marius
PS
I created a very simple application to test it. It works fine there:
qx.Class.define("test.Application",
{
extend : qx.application.Standalone,
members : {
main : function() {
// Call super class
this.base(arguments);
var button1 = new qx.ui.form.Button("First Button",
"tttest/test.png");
var button2 = new qx.ui.form.Button("First Button",
"tttest/test.png");
var sp = new qx.ui.splitpane.Pane("horizontal");
sp.add(button1, 1);
sp.add(button2, 1);
sp.remove(sp.getChildren()[0]);
sp.remove(sp.getChildren()[0]);
this.getRoot().add(sp, {edge: 0});
}
}
});
