What correct expression Image's center Xpos/Ypos

[BackStaged]

So, ok, i try to find a way to "find an expression which can allow me to find this":

- Find Center of an Image Box in a Frame
(even if i move the App window)

- Find Center of a Frame
(even if i move the App window, trying some VirtualWidth/Height.. but not work :/)

I trying some and some ways to figure this.. but, always fails..

Can you help me please guys?

(X Right - X Left)/2
OR
(Y Bottom - Y Top)/2
OR
(Width/2)+Offset
OR
(Height/2)+Offset


Do any of these help or did I misunderstand?

Hello LB, thanks for answer, but:

some of yours expressions give to me an "Error". Expression Incorrect or same thing of that..



So, then, let me better explain LB (so as this i hope you understand me).

For learning how Mouse Object work, i have created an application.

In this application:

- 2 Labels refresh ALWAYS.

    (1 indicate Mouse X Position)
    (1 indicate Mouse Y Position)

=> This work!

- 2 images
- 2 buttons (each under one image)

=>

- I want set my Cursor Position (X/Y) in the center of my first Image, even if i move the App Window..

=> This, not work.

Because:

I have no idea for catching the Center of the App Window. (true app window)..

I have no idea for catching the real main X Point/Y Point for test the positions of my Image object/of my Frame (also App Window).

It's give me weird result.
And it's curiously inneficace.

Then i'm stuck, in HTML for centering a POPUP with Javascript, it's in this syntax:

for "top" parameter:

Math.floor( (screen.width - widthv) / 2);

for "left" parameter:

Math.floor( (screen.height - heightv) / 2);

Where widthv and heightv are given by User (or Developer).

(because in HTML, the Popup parameter (window.open()) need this parameters: top, left, height, width)

But, in MMF2, theses parameters seems unfoundable..
(meaning: Return the ScreenWidth or ScreenHeight. It's only applicable on Frame, not on Screen...)
or i miss them???.. so..


Actually the problem is: Ignoring the App Window Position (so, then, the Frame Position distance with Real Screen Position).


Thanks for your future help (and for actual help).

Those expressions were meant to have the keywords replaced by the actual expressions.

There is the Window Control Object. It's one of the objects that comes with MMF2 when you installed MMF2.

Anyway, one of the examples for the mouse object shows how to set the mouse position to an object. You can use the same math for centering it.

Thanks for the Window Control object '(it called Contrôle Fenêtre in French)'. It seem fit what i was searching for!
