Traditional C style gui making vs subclassing

Recommended Posts

kcvinu

Hi all,

We can make guis with GUICreate function.  As well as, we can create guis in traditional C style with _WinAPI_CreateWindowEx function. Well, in the second case, we have the power and freedom to deal with WndProc function and thus we can do a lot more than the ordinary GUICreate function. But We can do the same things in ordinary GUICreate function with the help of  _WinAPI_SetWindowSubclass function and _WinAPI_RemoveWindowSubclass function. But i think we can't do anything in the WM_CREATE, WM_PAINT messages. (Please correct me if i am wrong).

So my question is; 

Which method is better ?

ordinary GUICreate function with subclassing OR _WinAPI_CreateWindowEx with original WndProc ?

Why i am asking this because, i need more control over my guis with maximum safety without performance loss.

If you create the parent GUI with _WinAPI_CreateWindowEx you can't use any of the native GUICtrlCreate-functions and you can't use any of the native functions that uses a controlID as parameter. In that way you have ruled out a substantial part of the native functions related to GUI creation and maintenance. This means that you have to create and update the controls with the functions in the GUI UDFs.

When you create controls with the functions in the GUI UDFs a true window handle is returned (not a controlID). You are going to use the control handle to update the controls.

Many functions in the GUI UDFs are divided into two parts. Often a short and fast part in case that the control handle turns out to be a native controlID, and a longer and slower part in case it's a true window handle. Because all your control handles are true window handles, you'll always be executing the longer and slower part of the UDF function.

Your requirement of no performance loss will not hold.

The development process will take significantly longer time. As a test, try to create a window with _WinAPI_CreateWindowEx and add a group control, a label and an updown control.

You are able to catch WM_PAINT messages by subclassing the controls.

It's not easy to catch WM_CREATE messages. But most code that can be executed in response to a WM_CREATE message can also be executed immediately after the control is created and before it's visible in the GUI. Why is it so crucial to execute the code in response to a WM_CREATE message?

The best method is definitely to use GUICreate and then use subclassing in cases where it's necessary. In that way you get all the benefits of the native GUI-functions, and because of the controlIDs you get faster code when you use the functions in the GUI UDFs.

@LarsJ ,

Thanks for your detailed reply. This reply enlightened me very well. I asked this question because, i am planning to make a different IDE for autoit which can help user to make powerull C style guis. That's why i am practising all messages from WM_CREATE to WM_QUIT. All the existing IDEs are using ordinary gui creation funcions. 

Anyway, according to you, using subclassing is the best bet for me.  Now, i need to practice all types of mesages with subclassing. Thanks again. You gave such a brilliant guidance. :)

      Hi All,

      MAIN QUESTION:
      Is it possible to Call specific function within a GUI

      So I have a script with multiple functions although I don't want to use every function every time.
      My Idea is to create a simple GUI which allows me to select what functions I want to use then run the funtions by clicking a button.
      I have already made a GUI which allows me to select specific .exe's I would like to run after selection it runs the .exe one by one.
      This script is on my work laptops and cannot access it right now.
       
      Who can help me with this?
      GUIcreate
      Func1 
      Func2
      Func3
      Then have a boxes which allows me to select the specif Func.(I used GUIChecked and Unchecked in my other script)
      Then a button which executes/calls the selected functions

      Hi Guis,
       
      I need to create keyboard shortcut to navigate the tabs and activate them, but I could not use the code below:

      Hello again!
      I have tried searching for quite some time now but couldn´t find a single working way to change the class of your GUI that doesn´t include changing it manually after its compilation.
      First or "AutoIt v3 GUI" is a pretty boring name tbh and i would like to spice it up a bit, also, and more importantly, I would like to identify my windows by something other than its title as it will change depending on some factors and im using two different programs independently as multi threading isn't supported.
      Any help is appreciated! Thank you!

      Hello, 
      i have a Problem with  _WinAPI_SetLayeredWindowAttributes, everything is working as excepted if u are on Windows 7.

      But if u are on Windows 10 the transparent background of a control is not clickable anymore. 

      Could someone help?

      Please see example below, put cmd.jpg into the same folder as Example.au3

      Please see trigger.jpg to see which sections are not clickable in Windows 10 (the red dots, the green dots are clickable) on Windows 7 the red ones and green ones are clickable.
       
      The same problem occurs if i use

      Hello everyones reading this post,
      I'm struggling at resizing properly my radio buttons to fit long text inside without affecting others radio buttons and also adjust position of them relative to the string.
      I tried with _StringSize UDF but I guess im too tired to figure out how to use it correctly..
      I also tried: _Control_SetWidth2Text I found on this forum, it work aslong im not maximizing GUI (radio text is gone when I maximize and maximize is a must)
       
      here is the code example, I hope someone can figure out (sorry if guictrlsetpos is not included in the example, I know thats probably the way to go but I wanted to make sure there is nothing better before use it)
      Thank you
