[Resolved] GUI design advisement for a scrolling arc style HUD

[xeroTechnologiesLLC]

Greetings!

I am developing a menu that will be laid out in an arc style similar to the image you see below:

No, it will not have ANYTHING to do with WoW, TOR or any other video game.

My question is, what would be the best way to go about creating an arc (maybe not so drastic of an arc shown above, maybe 5 -10deg worth, kinda like these parenthesis "( )".) list style of icons that the user could scroll up and down?

I've downloaded the extended WinAPI UDF and the OnHover UDF for various other parts of the project, but I'm not really sure where to begin with this one.

Imagine a list of icons that the user can scroll through that is in an arc instead of straight vertical up and down. How in the world could I go about that?

Thanks for any ideas or points of direction to start with....

This is what we have come up with so far - which seems to be working for the most part....if the user scrolls slowly. If you scroll real fast the button disappears. any thoughts how to prevent this?

Unfortunately, when adding a second control - it gets a little stupid.

The more and more I research this concept will not be doable in AutoIT. Mainly because I need it to scroll in a wheel and 3/4 of it will be hidden from the users view. I am not seeing any easy way to do this.

If anyone has any thoughts, please let me know.

So far we are aiming to take this project to a new coding platform. .net or flash depending on relevant capabilities.

[xeroTechnologiesLLC]

So I found this:

#include <GUIConstantsEx.au3>
#include <GDIPlus.au3>
_Main()
Func _Main()
    Local $hGUI, $hGraphic
    ; Create GUI
    $hGUI = GUICreate("GDI+", 400, 300)
    GUISetState()
    ; Draw arcs
    _GDIPlus_Startup()
    $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
    _GDIPlus_GraphicsDrawArc($hGraphic, 160, 100, 10, 10, 180, 360)
    _GDIPlus_GraphicsDrawArc($hGraphic, 180, 100, 10, 10, 180, 360)
    _GDIPlus_GraphicsDrawArc($hGraphic, 160, 104, 30, 30, 160, -140)
    _GDIPlus_GraphicsDrawArc($hGraphic, 140, 80, 70, 70, 180, 360)
    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    ; Clean up resources
    _GDIPlus_GraphicsDispose($hGraphic)
    _GDIPlus_Shutdown()
EndFunc   ;==>_Main

Which will draw a perfect arc.

So, that's cool. How can I use that to help me move a control along said arc? LOL

Controlmove moves to a singular x,y coordinate at a time. So I guess I could loop it, but it would be jumpy movement.

Anyone have any thoughts?

[xeroTechnologiesLLC]

So glad I found UEZ's samples on rotating and such.

Attached is some code that will, hopefully, help others that are trying to build themselves a scrolling menu or something of the nature.

The rest is up to however you want to make it, but this was probably the hardest part for me personally.

UEZ - not enough thanks make weight of how appreciative I am of you posting those examples.

This requires the Mouse On Event scrolling UDF...which I think this is the correct link: .

Hope this helps anyone else.

If y'all have ideas how to improve it, please fire away.

Cleaned up the code and removed unneeded (for this project) code.

Now the problem I am having is moving the visible area to the right side instead of just the left.

I thought that this section would basically say - what area is visible (in the first $tSize = dllstructCreate command) then where the 'visible box area' is with the last $tpoint = dllstructCreate command:

; _WinAPI_UpdateLayeredWindow parameters
$tSize = DllStructCreate($tagSIZE)
$pSize = DllStructGetPtr($tSize)
DllStructSetData($tSize, "X", 300)  ; adjust to show what is visible
DllStructSetData($tSize, "Y", $height)
$tSource = DllStructCreate($tagPOINT)
$pSource = DllStructGetPtr($tSource)
$tBlend = DllStructCreate($tagBLENDFUNCTION)
$pBlend = DllStructGetPtr($tBlend)
Global $alpha = 200
Global $alpha_steps = 5
DllStructSetData($tBlend, "Alpha", $alpha)
DllStructSetData($tBlend, "Format", 1)
$tPoint = DllStructCreate($tagPOINT)
$pPoint = DllStructGetPtr($tPoint)
DllStructSetData($tPoint, "X", 0)
DllStructSetData($tPoint, "Y", 0)

Am I misunderstanding the purpose of this block of code?

Arg, so stupid.

$tSource = DllStructCreate($tagPOINT)
$pSource = DllStructGetPtr($tSource)

...didn't have any values to tell it where to show up.

So to make the right side of the circle visible instead of the left we have:

Global Const $width = 1024

...initial width of the total window

; adjust to show what side is visible
; 0 0 - left side ...  600 0 right side
$tSource = DllStructCreate($tagPOINT)
$pSource = DllStructGetPtr($tSource)
DllStructSetData($tSource, "X", 600)
DllStructSetData($tSource, "Y", 0)

if you want just the left side visible, change the X value to 0.

The width of the window will help you determine the value of X and you will have to play with it a bit if you adjust the overall width to find the right value amount, but... so far this methodology is working.

Thanks again to UEZ.

Nice that I could help you.

Apologies, I was not trying to spam post.

I had a thought on something I wanted to create, didn't see anything else of it's style on the forums and wanted to post the findings as opposed to another dead ended thread.

Again, apologies and I will hold off on the final design post and post it in the examples forum once complete.
