 |
|
I found a nasty itch that would be great to heal: The vars A_GuiWidth and A_GuiHeight are only valid within the GuiSize subroutine. Why not always?
To fit a Tab within a GUI afterwards I has to do that following "construct" to outsmart it (working sample):
| Code: | gui, add, Tab2, h30,Tab1|Tab2|Tab3
loop, 10
gui, add, Button,, Button%A_Index%
gui, show
sleep, 500
msgbox, %mHeight% ; This is only for demonstration. Remove the Sleep command and watch the difference.
; The following line works, because due to the time lapse of the MsgBox command the subroutine had have enough time to fetch the height.
GuiControl, Move, SysTabControl321, % "h" mHeight + 25
Return
GuiSize:
mHeight = %A_GuiWidth%
Return
GuiEscape:
ExitApp
|
Especially the Sleep command is neccessary! W/o it the next command (MsgBox) is executed before the subroutine can fetch the value for the height!
Please make the vars A_GuiWidth and A_GuiHeight permanent. Also a pair for the upper left corner of the GUI would be great (A_GuiX an Y are sorrily preoccupied).
Many thanks in advance!

The problem with doing that is how do you decide what value A_GuiHeight has when you have more than one GUI?
As an alternative, you could use WinGetPos to get the window size. Another option is to plan out the GUI ahead of time and do all the calculation before you call GUI show (and then set the size in the command). |

Thanks for your hints, mate!

It's value changes with the active GUI.  | TheIrishThug wrote: |

That calculation-thing is much too difficult. And what if I wish to change the fontsize etc.? Actually I've 225 automatically generated Buttons spread over four tabs (keywords to index pictures in ThumbsPlus). 
The solution was the WinGetPos command: I tried it before but it gave always the whole screensize back and not the size of my window, so I tried other solutions and found that "non-working" A_GuiHeight".
What I did wrong was, that I thought, that the "Gui, show" followed by a WinGetPos w/o a WinTitle uses the Last Found Window, but it didn't. After I wrote down the window name it works.
Many thanks for that unexpected solution! But nevertheless: a always active A_GuiWidth/Height variable would be great.

It's a good point. AutoHotkey already has features which use the "default" GUI; GUI subroutines such as GuiSize set it, as does this:
A_GuiWidth/Height should just get the size of the default GUI. |

Gui Show does not change the Last Found Window; Gui +LastFound does.
Here's an alternative to WinGetPos which should be equivalent to A_GuiWidth/Height:
| Code: | Gui, Show, w500 h400 Hide
GetGuiSize(GuiWidth, GuiHeight)
Sleep 500 ; Delay for GuiSize.
MsgBox % "GetGuiSize: " GuiWidth "x" GuiHeight "`nGuiSize: " GuiWidth2 "x" GuiHeight2
ExitApp
GuiSize:
GuiWidth2 := A_GuiWidth
GuiHeight2 := A_GuiHeight
return
GetGuiSize(ByRef w, ByRef h, n="") {
if n !=
n = %n%:
Gui, %n%+LastFoundExist
ifWinNotExist
return w := h := ""
VarSetCapacity(rect, 16)
DllCall("GetClientRect", "uint", WinExist(), "uint", &rect)
w := NumGet(rect, 8)
h := NumGet(rect, 12)
} |
You may optionally specify the GUI number as the third parameter. If omitted, the current default GUI is used. |

Thank you, master!
You did it very well. But that amount of code let me yell for a simple solution in the next AHK-version for a plain working A_GuiWidth/Height.
...
Chris, please!
