Adding dynamic Controls to DesktopTabPanel / DesktopPagePanel

General

This is a little curious. I have TabPanel1 with two Tabs (DesktopTabPanel) and a button (DesktopButton) in my window. In the Button1.Pressed event I have the following code:

Var ctrl As New DesktopButton

ctrl.Caption = "Hello"
ctrl.Width = 80
ctrl.Height = 20
ctrl.Left = 20
ctrl.Top = 20
ctrl.Visible = True

ctrl.Parent = TabPanel1
ctrl.PanelIndex = 1

Self.AddControl(ctrl)

The button is not placed inside the TabPanel (2nd Tab), but above it.

Does anyone have an idea how to make this work correctly?

2

may be set the control left and top to a global value, and not relative to the tabpanel topleft ?

3

Are you not adding the button to the window and not the tabpanel?

4

Tried this, no difference.

Since the control is created in code, it has to be added to the the Window via DesktopWindow.AddControl. You can’t add a control to another control.

5

add the control, and then only set the parent ?

And here we go. Thanks @Jean-Yves_Pochez

Var ctrl As New DesktopButton

ctrl.Caption = "Hello"
ctrl.Width = 80
ctrl.Height = 20
ctrl.Left = 45
ctrl.Top = 45
ctrl.Visible = True

Self.AddControl(ctrl)

ctrl.Parent = TabPanel1
ctrl.PanelIndex = 1

you could still file a bug report for this … this should also work as your first post ?

At the first look yes, but since the Button don’t exists until we call AddControl, I think this is the expected behaviour.
