Hello everyone,

I'm a real begginner with PowerBuilder, so excuse my ignorance, and in addition I'm French, so forgive me my way of expressing myself.

 In a window I would like to create synamically some object like with the code bellow :


integer li_counter, li_y
commandbutton lcb_button


FOR li_counter = 1 TO 5
lcb_button = CREATE CommandButton
lcb_button.Text = "Bouton " + String(li_counter)
lcb_button.Width = 100
lcb_button.Height = 30
lcb_button.X = 10
li_y = 50 + ((li_counter - 1) * 40)
lcb_button.Y = li_y

How to create the button ?????

Does someone knows how to do that ?

In advance thank you for your advices.

Use function OpenUserobject instead of CREATE.

But you can't reuse lcb_button variable as in your examle.

This should work:

commandbutton lcb_button, lcb_initial
int li_counter, li_y

FOR li_counter = 1 TO 5
	lcb_button = lcb_initial
	OpenUserobject (lcb_button)
	lcb_button.Text = "Bouton " + String(li_counter)
	lcb_button.Width = 100
	lcb_button.Height = 30
	lcb_button.X = 10
	li_y = 50 + ((li_counter - 1) * 40)
	lcb_button.Y = li_y

I created an UserObject in the code above, I would like to replace the commandButton by this UserObject named u_sys_agd.

I struggle to do it.

Does someone knows how to do that ?

In advance thank you for your advices.

If I understand you right you want to dynamically create visible userobjects on your window?

Just replace "commandbutton" with you userobjects classname ("u_sys_agd") in tzhe example code.
