Simply center a button !?

[ozzii]

Hi,
I'm new to AHK and I have a question:
How can I do to simply center a button on a GUI?
I've search the internet but found nothing simple (or it's me )

There is some conditions:
-I don't know the size of the gui
-The GUI is not resizable
-The button have a fix width, height

Thanks in advance.

You may use the GuiSize label:

Code: Select all

#NoEnv
Centered := False ; initial value = False / not centered
BtnW := 200 ; fixed button width
BtnH := 30  ; fixed button height
Random, GuiW, 300, 800  ; rendom GUI width
Random, GuiH, 100, 400  ; random GUI height
Gui, Add, Button, w%BtnW% h%BtnH% vCenteredBtn, Centered Button
Gui, Show, w%GuiW% h%GuiH%, Centered Button
Return

GuiClose:
ExitApp

GuiSize:
   If (Centered = False) { ; the button hasn't been centered as yet
      ; Calculate the horizontally centered X-position
      BtnX := (A_GuiWidth - BtnW) // 2
      ; Calculate the vertically centered Y-position
      BtnY := (A_GuiHeight - BtnH) // 2
      ; Center the button
      GuiControl, Move, CenteredBtn, x%BtnX% y%BtnY%
      ; Mark as centered
      Centered := True
   }
Return

Thanks...
I thought that the guisize was just for a resizable gui!!!

I still think that a build in command will be great!!!

Is there a simpler method available now?

Code: Select all

x+10
x-10

moves the button after the previous element ends or before it begins. Is there no way to center the buttons relative to the previous elements?
