How make it?

[Silvio.Falconi]

I saw on another application this


the button open a menu popup and on the menu there are two slider controls , Can make it on Fwh ?

Silvio,

You can connect a dialog to the button on action.
Dialog-top = button-bottom, dialog-left = button-left.
There You can include what ever You want.
If needed You can paint a colored border around the dialog.
The logic can be used on any other object.
In xBrowse it is connected to a cell.



connecting the dialog to the button ( main function )

Uwe,
If I wanted a dialog I already knew how to do it
I think I asked for a particular thing
If you look closely you will see that the button opens a POPUP MENU control
and therefore not a dialog
other times you've already answered with other things that I don't even think about asking!!!!

[ukoenig]

Silvio,

the button open a menu popup and on the menu there are two slider controls

in case something is not possible I'm looking for a alternative solution
that comes close to the needed result.

other times you've already answered with other things that I don't even think about asking!!!!

Trying to find a solution It is not a answer to something else.
But never mind I can save my time.

regards
Uwe

I'm searching if I can make a codeblock type bInit to run a function to insert the slider into menuitem of menupopup

I found some question on Internet

for now I resolve in this mode:


the user can use the percentual on Total or make a descount on days
it is beautifull but not professonal work

Dear Silvio
Currently it is not possible, but it is not impossible
For some time I was studying that possibility, but for lack of time I left it unfinished.
I hope to be able to return to the subject and get what you propose. It is not simple because although the item has hWnd it is not considered as a container of controls. We'll see
