Hmm.. That trick would be annoying fast with the kind of glasses I wear (wearing contacts)  but okay!

I really like this. I love simplicity. It also has a nice, soothing design. Personally, I would use this for a To Do list and things like that.

I didn't test it much (yet), but I saw bullet points which is good. Checkboxes might be an idea for things like To Do lists.

One main suggestion:

It really needs support for DPI scaling. I added it while testing the uncompiled script on my system and it looks fabulous with the DPI scaling.

You can add the following just after your includes (or at least before GUI creation):

; System aware DPI awareness
DllCall("User32.dll", "bool", "SetProcessDPIAware")
; Per-monitor V2 DPI awareness
;DllCall("User32.dll", "bool", "SetProcessDpiAwarenessContext" , "HWND", "DPI_AWARENESS_CONTEXT" -4)

You can comment out the first one (system aware) and uncomment the second one if you want per-monitor DPI aware, but that can be more complicated.

[TheAutomator]

WildByDesign,

; System aware DPI awareness
DllCall("User32.dll", "bool", "SetProcessDPIAware")
; Per-monitor V2 DPI awareness
;DllCall("User32.dll", "bool", "SetProcessDpiAwarenessContext" , "HWND", "DPI_AWARENESS_CONTEXT" -4)

I didn't even know that dll call existed before you showed me.
Gonna add this to the code for sure, thanks for letting me know!

BTW, about the design (spoiler alert), it's getting an update:

and you're the first to get to see it :p

updated code (and credits to you) coming soon!

..in the Info GUI, add a link to Made By: @TheAutomator for users to open this thread.
Maybe there is an update ? Maybe I wanna know where I got this from ? ...if I replaced the example/welcome file or am working on another file.

Good idea! Added to the todo list  Thanks argumentum.

Update,

The code is getting a huge update, that's why it takes a little longer for me to post the new version.
I also found a solution for the scrollbar that finds the balance between simplicty and performance, it now updates how it should and works a little diffirently.
Implementing your own scrollbar is not the most easy task I learned, but a lot of people have showed me inspiring code and examples.

Updates coming soon:

• better search gui in same style and functions
• better gui design with stylized popup messages
• no 100 images anymore, but just a few with the text on them being generated on the fly
• final touches on the graphics
• save as function added

I also wanna thank Nine for giving me some new insight in the more low level functions of autoit, and everyone in this topic for all the idea's and effort:

Please have a look at Nine's UDF, it's very cool! Also the windows "dark mode" one 

Regards!

[TheAutomator]

Update,

• you can now save some settings to an ini file
• search function done
• code is better organized
• UPLOAD HAPPENING SOON

New bug detected for saving and loading zoom settings for the edit control:

Everything looks sharp, beautiful and stylish!

The only real negative that I spot initially is that the custom scrollbar position does not change when using the touchpad swipe up/down gestures. A standard scrollbar in AutoIt does not have this problem.

[WildByDesign]

If you check RoundGUI Example3.au3 from (https://www.autoitscript.com/forum/topic/212767-round-corner-gui-and-controls-udf/)  you will see in that example that the design of the scrollbar fits perfectly within your design, but also works properly with the touchpad swipe up/down gestures. I feel like it's a bit smoother as well when scrolling through a larger RichText box. The custom scrollbar in MiniMark V4 Beta seems a bit glitchy while scrolling.

yep.. but I don't understand the code of Nine very well, and I only want to implement the scrollbar part (and like to know what i'm doing instead of accidentally creating memory leaks), feel free to help if you wanna add such scrollbar and/or understand Nine's code 

From what I understand from it, it uses a lot of DllCallbackRegisters, DllCallbackGetPtrs, and api calls like "_WinAPI_SetWindowSubclass", a bit of Chinese to me

@TheAutomator there are always good things to learn from @Nine's code, but it takes time to (try to) understand it, because our knowledge of AutoIt/Windows isn't as high as his. I always said he's a great coder !

Nine uses Subclassing a lot, which seems to be the shortest way to accomplish many tasks, which would require much code when not used. For example, with the code below I can mimic a scrollbar (using 4 label controls) without subclassing, by registering WM_COMMAND & WM_NOTIFY, but it requires more code than subclassing :

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <GuiRichEdit.au3>
#include <Misc.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

In this script, the scroll "thumb" (a label control) has a dynamic height, it's not static as in your script (or Nine's) and its height varies with the number of total lines in the richedit control . Also I can click on the "scroll background rectangle" (another label control which overlaps with the thumb control) to scroll 1 page up/down, or on the 2 scrolls arrows (2 other label controls) to scroll 1 line up/down, as in a normal scrollbar.

I'm not satisfied with the fact that clicking quickly on the scroll arrows doesn't scroll 1 line up/down each time the user clicks on a scroll arrow. I just discovered why today : clicking quickly twice on a label control doesn't trigger (twice) the corresponding Case in main loop, because it's recognized as a double click on the label control, which should be taken care of in WM_COMMAND as @Melba23 indicates here  . This "annoyance" doesn't occur with button controls.

[ Note : the preceding "Strikethrough" comment has been fixed in the code by using a Dummy control, triggered by WM_COMMAND and processed in main loop. ]

Using Pic controls (as you do) instead of Label controls seem to work , as both are static controls. What is important is the order of creation of the 2 overlapping controls, as found in the script, e.g. the big "scroll bar rectangle" (dark grey in the pic) and the smaller "scroll thumb" (red in the pic)

I scripted this only for educational purpose, because simply adding the "WS_SCROLL" style to the richedit control would solve it all, but I understand why you don't want to use WS_SCROLL (you explained it before)

Maybe the script above will help you, maybe not, or maybe it will be a good occasion for you to spend some time on Nine's subclassing part & the learning of DllCallbackRegister etc... For example, see in this post how @LarsJ quickly used subclassing to efficiently solve OP's question, amazing !

Good luck

You're welcome, it was interesting to script.
As I just did a new update today (7th april), may I suggest you delete the old quoted code from your last post, so we keep only the updated version ?

Thanks and have a great day

Found some time to make a simple example to wrap my head around the example you gave me

I managed to boil it down to the code below for testing. Gonna skip resizing the tumb and double clicks for this test, do you see any flaws in the test scrollbar I made?

You caught me while I was in the PM section
Gonna have a look at it and let you know later, see ya.

@TheAutomator i tried your code, it works fine when you scroll by dragging the thumb. Now the thumb moves up or down while you drag it, which was a missing feature as noted by WildByDesign.

Well done.

Yeah, and moving the cursor down or up so that the edit updates also changes the tumb position

@Nine detected when the tumb was pressed in the main loop by ctrl id, and so did you, but that means an extra block of code, using _ispressed, and an extra fuction to update some variables, so i skipped that part ( not sure if that's a good approach but it's working 😛 )

Gonna put this and some other fixes in the MiniMark code soon.

you helped me a lot, thanks for that!

@TheAutomator glad I could help

Just a reminder : in case one day you'll have to check $Bar and $Tumb in your main loop (please add them to your script, for a quick test)

    Switch GUIGetMsg()
        ...
        Case $Bar
            ConsoleWrite("Bar" & @crlf)
        Case $Tumb
            ConsoleWrite("Tumb" & @crlf)
    EndSwitch
WEnd

Then this is what would happen, when you click the Bar control or the Tumb control :

1) Order of creation of the 2 overlapping controls, as found in your script above :

$Bar = GUICtrlCreateLabel('', 70, 70, 40, 270, $SS_BLACKRECT)
$Tumb = GUICtrlCreateLabel('', 70, 70, 40, 80, $SS_GRAYRECT)

Bad ConsoleWrite : "Bar" is always displayed in the Console, even when clicking on Tumb !

2) Let's reverse the order of creation :

$Tumb = GUICtrlCreateLabel('', 70, 70, 40, 80, $SS_GRAYRECT)
$Bar = GUICtrlCreateLabel('', 70, 70, 40, 270, $SS_BLACKRECT)

Now it's worse : the Tumb doesn't even show in the GUI !

3) Correct way of creation + use of $WS_CLIPSIBLINGS

$Tumb = GUICtrlCreateLabel('', 70, 70, 40, 80, $SS_GRAYRECT)
$Bar = GUICtrlCreateLabel('', 70, 70, 40, 270, BitOr($SS_BLACKRECT, $WS_CLIPSIBLINGS))

Tumb appears normally in the GUI, ConsoleWrite shows correctly "Bar" or "Thumb" depending on the clicked control.

I did several tests like these, using overlapping label + label, then label + pic, then label + button. I also checked at the same time GUIGetCursorInfo() to make sure the last element of the returned array corresponds to the correct control hovered over. Gladly it seemed to work in all cases

As you scripted it differently (without the need to check $Tumb and $Bar in the main loop) then you're not concerned with all this, just remember this post if one day you need it, who knows.

For what it's worth...

Noted, good advice! Now I understand why you needed WS_CLIPSIBLINGS
