Same ContextMenu on different Controls

[klaus]

This is a small example, using the Door library, to manage a same ContextMenu on different Controls.

The request comes from the German forum on how to get the Control name from where the ContextMenu was triggered.

I think this could be usefull for others.

Best regards.

Hi klaus,

thanx for this sample program. I try it, but doesnt work on realtime designed componets. For designer placed object works fine. Can me explain why?

 

[klaus]

What's the problem ?
See the attached program, works OK with controls added at runtime.

Best regards.

Hi Klaus,

thanks for reply. Your demo works fine. I attach part of my prog, which dont work. Please check it (if You want) and say me why.

Thanks.

I tried your program, works fine on my desktop (IDE and compiled) and on my devices (autoscale compiled) (Qtek9090 WM2003, htc HD WM6.1.
So, could you explain what doesn't work.

- do you get an error ?
- are the context menus not displayed ?
- are the context menus not working ?
- etc

Best regards.

I run program in IDE for now.

After start shows only panel with scrollbar. Then You must call context menu and select Add Text. On newly created textbox again You must call context menu and select first item. Then program shows messagebox. In this messagebox should be name of textbox which is owner of context menu. But doesnt show nothing.

It is doing exactly what you have programmed it to to - displaying any text that has been typed into the textbox

 

[PatrikL]

In contextmenu click sub is code for giving name of textboxt which call context menu.

Sub cmtext_Click
'Dim Source
cmtextobj2.Value=cmtext.Value
cmtextobj1.Value=cmtextobj2.GetProperty("SourceControl")
Source=cmtextobj1.GetProperty("Text")
Msgbox(Source)
End Sub

According klaus demo program, this code show owner of context menu. In klaus demo program works fine. But not in my program. I cant understand why my code dont work (its same code as klaus code).

According klaus demo program, this code show owner of context menu..

Klaus' program is returning the text property of the owner control which just happens to be the name of the control in his demo. If you type into your textbox then use the context menu you will see the text you have typed.

To get the name try

Source=cmtextobj1.GetProperty("propName")

This will only work on Basic4ppc intrinsic controls, not those added from a library.

Thanx a lot.

Works finally.

Btw. I search in
ContextMenu.SourceControl Property (System.Windows.Forms)

for properties "Text" or "propsname". I cant find nothing about that. Exist any better documentation?

P.S. agraham please look here http://www.b4x.com/forum/questions-help-needed/6310-textbox-event.html and help solve also this my problem.

Btw. I search in ..for properties "Text" or "propsname". I cant find nothing about that.

Because they belong to the Textbox which is the source control, not the ContextMenu.

Exist any better documentation?

For using the Door library you've found it - MSDN!

P.S. agraham please look here

Sorry but I won't be doing that.

Sorry for answering that late, I was not at home this afternoon.

I checked both, my example and your program.
In fact it was not a good idea to use the Text property.

The Name property doesn't work because it returns Door.object.

I modyfied both programs using the Tag property,
- I set the Tag property to control's name
- Reading the Tag property gets it back.

Best regards.
