Size information of controls?

[JAFN]

Hi again,

I feel like I am missing something obvious.

Maybe I'm just getting worse at searching.

All I need is a udf that when sent a controlID will return an array holding left, Top, height and width.

This seemed simple when I started and now I've been searching forever.

Normally I just want a pointer to get me going.

Here I think I would learn more by studying the func if someone would be kind enough.

As always, thank you for your time and eternal patience.

Check out ControlGetPos.

Thank you.

That could have been better named.

For once though I am happy to have overlooked the obvious as this exactly what I need.

I have two other problems but I want to search and nibble for a couple more days.

Thank you for your time and patience.

Could *not* have been better named

This is the first time I am writing something to an array.

Based on examples it seems like this should work.

Why does it error?

#include <array.au3>
#Include <GuiSlider.au3>

$Width  = 550
$Height = 600
$WinX   = 480
$WinY   = 400
$GUIid  = GUICreate("DropBeep", $Width, $Height, $WinX,  $WinY)
$slider = GUICtrlCreateSlider(333,114, 128, 20, $TBS_BOTH)
$ret    = Center($slider, 72)

$slider1FreqLabel = GUICtrlCreateInput("Testing", $ret[0], $ret[1], 128, 72)
GUICtrlSetBkColor($slider1FreqLabel, 0xffffff)

Do
    $msg = GUIGetMsg()
Until $msg = $GUI_EVENT_CLOSE

Func Center($Cid, $Width)
    $Pos = ControlGetPoS("","",$Cid)
    $X = $Pos[0]
    $XW= $Pos[2]
    $Y = $Pos[1]
    $YH= $Pos[3]
    $PosX = (($XW/2)+$X - ($Width/2))
    $PosY = ($Y - 20)
    $array[0] = $PosX
    $array[1] = $PosY
    return $array
EndFunc

So what is the error? A lot of times, an error message will point you in the right direction to start.

JAFN,

Two problems:

- 1. You need to specify the GUI when you use ControlGetPos. You have not yet allowed the GUI to show, so AutoIt is not sure exactly what GUI to use. Just add the GUI handle to make it explicit.

- 2. You need to declare arrays before you assign values to the elements otherwise AutoIt does not know what how much meory to allocate - it cannot read your mind!

This works for me (look for the <<<<<< lines as usual):

#include <GUIConstantsEx.au3> ; <<<<<<<<<<<<<<<<<<
#include <array.au3>
#Include <GuiSlider.au3>

$Width  = 550
$Height = 600
$WinX   = 480
$WinY   = 400
$GUIid  = GUICreate("DropBeep", $Width, $Height, $WinX,  $WinY)
$slider = GUICtrlCreateSlider(333,114, 128, 20, $TBS_BOTH)
$ret    = Center($slider, 72)

$slider1FreqLabel = GUICtrlCreateInput("Testing", $ret[0], $ret[1], 128, 72)
GUICtrlSetBkColor($slider1FreqLabel, 0xffffff)

GUISetState() ; <<<<<<<<<<<<<<<<<<

Do
    $msg = GUIGetMsg()
Until $msg = $GUI_EVENT_CLOSE

Func Center($Cid, $Width)
    Local $array[2] ; <<<<<<<<<<<<<<<<<<
    $Pos = ControlGetPoS($GUIid,"",$Cid) ; <<<<<<<<<<<<<<<<<<
    $X = $Pos[0]
    $XW= $Pos[2]
    $Y = $Pos[1]
    $YH= $Pos[3]
    $PosX = (($XW/2)+$X - ($Width/2))
    $PosY = ($Y - 20)
    $array[0] = $PosX
    $array[1] = $PosY
    return $array
EndFunc

All clear?

Thank you.

I see exactly how I twisted myself up.

Thank you all for putting up with my questions.

And answering so quickly.
