GUI performance

Context

Lately I have been experimenting with the creation of a GUI with AutoIt.

In my last test I created some code to draw a grid of labels on a window.

When I update the grid the GUI seems very slow to me.

I actually have to wait a few seconds till the grid is updated.

Request

I would really appreciate some help on speeding up the painting of the GUI.

GUI

The following example consists of a simple window.

The window contains a grid of colored labels.

By pressing the button the colors of the labels are inverted.

Problem

When pressing the button, the colors of the labels are inverted.

The problem is the time it takes to refresh the grid: a bit less then 3 seconds.

I believe this should be done almost instantly.

Is there a way to speedup this process?

Edit: Changed the type of <code snippet> to <autoit> for colored source code

Or you could draw the grid using GDI+.

EDIT: interesting effect of the second version which is quite fast for me, if you click the invert button repeatedly then the squares around the edge appear to move in different directions depending on which corner you look at. (Or is it the mushrooms I had for breakfast?)

Maybe a little faster haven't tested but this is more optimised. Also don't declare variables in Loops as this slows the Loop down, trick I learnt from Melba23 ;)

#include <GUIConstantsEx.au3>

    $iButton = GUICtrlCreateButton("Invert", 10, 10, 65, 22.5)
    GUICtrlSetOnEvent(-1, "_Invert")

    GUISetState(@SW_SHOW, $hGUI)

Much slower than the WInMove method if my tests are believable. It doesn't look any slower to me but then I can't think that quickly.

To be honest I just overseen your code from above :huh2: because I was in a hurry.

It might be that your method is faster than what I did which I update again.

UEZ almost all your visual examples are that of GDI+ :huh2: just saying its kinda funny

good examples though they may be i'm beginning to wonder if you married the _GDIPlus funcs.... haha

This is one of the things why I appreciate AutoIt: the excellent community.

Thanks a lot for the fast and constructive replies.

Again, I learned a lot thanks to you guys.

During the thread I noticed the description of my problem might not be as precise as it needs to be.

While all of the given solutions are applicable on my example, some might not exactly resolve my issue.

Please endure with me and let me rephrase my problem :huh2:

New Context

The tool I'm actually writing helps to locate some pixels on the screen.

Extended GUI

The idea is that the user inputs a pixel color.

The user moves the mouse to a location on the screen and presses the F10 button.

A grid is created which represents the pixels around the mouse.

The grid is created using a combination of colored labels and buttons.

The buttons represent pixels which have the exact same color as the one given.

Posted Image

Source code

The model view controller pattern has been applied.

The view handles the GUI (PixelLocator/View/PixelLocator.au3)

The model handles the state and the calculations (PixelLocator/Model/PixelLocator.au3)

The controller is the link between the view and the model (PixelLocator/Controller/PixelLocator.au3)

The application is launched by running PixelLocator/Application.au3

Please note I have attached the source code in this post.

Problem

Although the application of the winmove did work quite fast in previous example, it doesn't seem to be helpful in this context.

The application of the performance tricks makes the GUI faster but the result is still a little slow.

Question

From what I read I believe the usage of GDI+ might provide the solution I need.

The reason why I am a little bit reticent about using GDI+ is because of Windows it self.

A while ago I used a DLL found on these forums to locate an image on the screen.

It worked perfectly till Microsoft updated Windows XP.

I believe the DLL used a function in the user32.dll which has been updated since.

So I am a little bit worried the GDI+ libraries might get broken with a Windows update.

Is this something to worry about or am I being a fool?

You can use the part of my code which I used in to display an area of the destop in a window.

Let's say I go with the GDI solution from UEZ.

What I'm worried about is following lines of code

GUICtrlSendMsg($idPic, 0x0172, 0, $hImage1)
DllCall($ghGDIPDll, "uint", "GdipCreateBitmapFromScan0", "int", $bmpw, "int", $bmph, "int", 0, "int",  0x0026200A, "ptr", 0, "int*", 0)

What happens when Microsoft updates it's system which makes the API's of the called DLLs incompatible?

(This has happened to me before so it's a real concern)

How am I supposed to get the script working if I don't have access to Microsofts documentation?

Let me rephrase that:

Aren't there any build-in functions in Autoit that can handle previous lines of code?

I really don't like calling a dll or sending a message with obscure codes to a control.

If the API of the DLL is updated then Autoit should handle this (probably with an update), not me or the code I write.

See what I mean?

It most certainly is up to you to update your code if things in Windows change, just like it's up to you to change your code if things in AutoIt change. If you compile a script, no amount of updating to AutoIT is going to fix your compiled code, you're going to need to update it to match the changes to Windows, just like when Vista/Win7 was released.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

If I'm insisting it's because I'm considering filling in a feature request.

The function calls I mentioned before (used by the example of UEZ) look to me like a some base function taht has been skipped from some UDF.

Call me a purist if you want but I'd rather rely on the Autoit framework then on the MSDN library.

Although I really appreciate the constructive replies I've gotten so far

and thumbs up to all of those authors

I don't quite understand your hostile attitude AdmiralAlkex.

Psychoman, the AutoIt 'framework' is built upon the same API calls you will find on MSDN. Microsoft is pretty keen on keeping backwards compatibility in their operating systems. Stuff that runs in Windows 2000 will run in Windows 7, and so on into the future. Rarely, functions are declared obsolete by Microsoft, and even then still continue to be supported. This is one reason the O/S is bloated. The only buggers you need to worry about are undocumented functions. Once it hits MSDN and gets documented, however, its pretty much a good bet it will be supported well into the future.

Alkex should try articulating a point rather than disparaging others.
