Wow! that sounds awesome Fred, so instead of reading a string for null termination - the length is already cached?

Hi PrinceD, congratulations on all the work you're doing with ProGUI. I was wondering if you have a general idea of when the first release will be ready. Thanks.


Thanks le_magn :) I'll release another alpha in the next few days (just sorting the Windows 11 skin and how auto skin selection will ...

Hi guys!

Delays and delays! fixed a couple of rare crashes. And a bug with with how drop-shadows are calculated with full window skinning. So I'm getting the Windows 11 skin ready now

Hi guys, got the little exe app icon working in the top left of the Titlebar widget now (for full window skinning). There's a new LoadImgResource(Path.s, *lpName, *lpType, Flags = #Null) command in the GFX API which will load an icon into an img from an exe/dll resource (group icons working only at ...

Hi Chris,

Tested here (on Win 11 x64); Looked great, was smooth & reactive to all resizing I tried, great to see 8)

Is the UI layout logic your own, or is there some example PB code on the forum for it?


That's great to hear pjay! :) The UI layout logic is all my own. There's a basic layout ...

Kind of wondering how best to solve an ease of use case. ProGUI V1xx used ToolBarImageButtonEx(ButtonID.l, Text$, *NormalImageID, *HotImageID, *DisabledImageID, Style.l). Where you would manually load in your images. Now it's all CSS .. ToolbarAddButton(name.s, text.s), Toolbar has a class and each ...

this seems to work just fine on a Win11/Xeon box, and as you documented: showing the Win10 GUI emulation.

That's excellent, thanks Skipper!

Hi guys, could you give this Alpha 4 demo a test please?

I'm mainly interested in what the rendering performance is like on window resizing (it should open up 2 windows, a blank window and a window with a flex layout and some nested widgets with ...

Hi guys, I've improved window resize rendering performance by roughly 2x using a dynamic DirectCompositon comit wait mode. I keep a rolling average of how long the GPU takes to render a scene and then calcaulate when the DWM (Desktop Window Manager) next present frame is due, if the average will ...

I use Claude quite a bit (very good at PureBasic now) for small self contained procedures and for double checking logic, finding errors and finding optimization opportunities (the LLMs are good for that kind of thing). The key is to read fully all the generated output and not rely on it as gospel ...

SkinSetValue("window", "", "", "transition", "border-radius 1s")
SkinSetValue("window", "inactive", "", "transition ...

Hi guys happy new year! sorry I didn't get the new release out, I ran into some DirectWrite text rendering issues just before everything was ready. Solved now hopefully.

Happy new year! everyone!

Hi guys another quick update:

The Titlebar widget default CSS currently looks like this:

SkinSetValue("titlebar", "", "", "background", "var(color-titlebar-active)")
SkinSetValue("titlebar", "", "", "color", "white")
SkinSetValue("titlebar", "", "", "text-align", "center")
SkinSetValue("titlebar ...
