Resize a child window when the parent is resized

[FaT3oYCG]

Hi, I have been looking fo an answer to this since I got up this morning about 6 hours ago, I have a child window that is created inside of my main window which I would like to resize when the parent is being resized but the code that I am using only resizes it after the parent has been resized. I have the code to resize the child but it does not take effect while the window is being resized only after the window has been resized which doesn't look very good.

here is the code that I am using, I have tried a few other methods including using the $GUI_EVENT_RESIZED message but that also did not work.

 Script Function:
    SciPad - A Scintilla based editor.

#ce ----------------------------------------------------------------------------

; Script Start

#include <GUIConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#include "SciLexer.au3"

Local $SciPadWidth = 600
Local $SciPadHeight = 450
$hwndSciPad = GUICreate("SciPad - A Scintilla based editor", $SciPadWidth, $SciPadHeight, (@DesktopWidth - $SciPadWidth) / 2, (@DesktopHeight - $SciPadHeight) / 2, _
BitOR($WS_CAPTION, $WS_SYSMENU, $WS_MAXIMIZEBOX, $WS_MINIMIZEBOX, $WS_SIZEBOX))

$Sci = Sci_CreateEditor($hwndSciPad, 10, 10, $SciPadWidth - 20, $SciPadHeight - 20)

GUISetState(@SW_SHOW)

While 1
    $Msg = GUIGetMsg(1)

    Local $SciPadPos = WinGetPos($hwndSciPad)
    WinMove($Sci, "", 10, 10, $SciPadPos[2] - 30, $SciPadPos[3] - 54)

    Switch $Msg[0]
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Does anyone have a simple solution to this, I would like to keep te code small if that is possible and as simple as it can be aswell so when I come back to it I will be able to understand it.

I am not simply requestiong the answer or some code for this question but would preffer to be told what I am doing wrong and directed towards the correct method (unless I won't find it out because it is too advanced).

Thanks,

Craig.

FaT3oYCG,

Not sure whether you would call this "too advanced" - I would certainly call it "pretty advanced"!

That will work , thanks I'm sure I will be able to pull the relevant information out of that and then research anything that I don't understand, if not ill be back .

EDIT:

It seems that the information i needed was a simple as this: GUIRegisterMsg($WM_SIZE, "function name")

Thanks,

Craig.

O.K. Thanks for that I have it set up as I want it now, I was just wondering if the child window flickering was because I am creating an instance of Scintilla and if not would you know of any ways to try and stop this problem occouring?

FaT3oYCG,

You can sometimes get over flickering of child windows by creating the parent GUI with the $WS_EX_COMPOSITED style. But beware, if you have overlapping controls (like a disabled backgroud Pic control and foreground buttons) they need to be created in the reverse order because of the way the GUI is redrawn.

Perfect thank you, I feel silly asking these questions when you seem to know the answer straight away .

Thanks,

Craig.

There is no need to ever feel stupid when asking a valid question of people with more experience than you.

FaT3oYCG,

George has it in one. From an earlier life: "The only stupid questions are the ones you do NOT ask".
