Hey. As mentioned in #25 window can be closed like so:

func update(w *nucular.Window) {
    w.Row(50).Dynamic(1)
    if w.ButtonText("Close window!") {
        go w.Master().Close()
    }
}

This does close main window indeed, but keeps the MasterWindow.Main function looping forever. Is there any way to completely stop window routine and pass control past call to Main?

Also possibly related: default macOS menubar hotkeys do not seem to trigger when window is open. Do I have to manually provide menubar hotkey checks?

Thanks in advance.

I see that demos exclusively make use of monospaced font. Currently it uses DroidSansMono.ttf, would it work (said differently "is it tested?") with a font not mono. like ie DroidSans.ttf not monospaced?

Go compiles successfully the overview and demo examples, but when I try to run the binaries I get error. I have no problem running the simple example.

Here the output of the console when trying to run overview.exe:

I'm using windows 10, 64 bits.

Hi,

It is great to see so nice GUI with pure go, in a relatively simple code base. Is there any example using it on mobile (IOS/Andriod) platform? gomobile should have this support but I am so new a gopher that I can't do it by myself.

Thanks

the GUI stalls on OSX as soon as its opened. This results in the beachball from hell.

I dont have time to look into whats going on. Am away, but wanted to raise this.

Just based on a quick look at the code, this should be a super simple fix. The problem is in the LabelWrapColor function. The function tries to use the color parameter as the text to display: https://github.com/aarzilli/nucular/blob/1e37c3d3f055a9bf1fb359cdcb2395f08098ce18/nucular.go#L1557

It should instead read:

text.Text = str

While installing github.com/aarzilli/gdlv on macOS the installation is failing due to build break in github.com/aarzilli/nucular due to breaking changes (ref: ae2c74ec) in gioui.org/op.

ae2c74ec — Elias Naur a month ago
op: relax Push/Pop to Save/Restore semantics

A previous change implemented save/restore semantics where a saved
state can be restored anywhere, not just in a stack-like manner.

This change similarly relaxes the exported Push/Pop operations; the next
change will rename them accordingly.

Fixed extra chars in #39 but if press any of keys :

• "Alt Gr."
• "block uppercase"
• "numerical block"
• Any operation symbol key "+ - * /" in numerical block

TextEditor, print a "square".

Thank you again.

Hello!

First, thanks for the project, I'm a big fan of using Go outside its server-side niche, and this project contributes to spread this idea. The Nuklear UI toolkit is an example how to properly design GUI toolkits, it's indeed a good source of inspiration for us, gophers, too.

But what I'm concerned about is the fact that some of crucial Nuklear ideas been ignored in this port, for example, no dependencies on the OS / platform. Nuklear handles UI without relying on the platform implementation, and that's a huge deal. Nucular as opposite, embeds platform integration code within, makes it harder to port on different platforms. Actually, it relies on /x/mobile for platform integration, the project that is very close to the Go upstream and is very conservative on features and development.

I'm just concerned that even this project develops fast, it will be limited by platform support, soon or later, so better be thinking about backend decoupling at some nearest future.

(just my thoughts)

Not usre how to build the demo.

Also the vendoring.. What are you using ? So i can also do it.

x-MacBook-Pro:_demo apple$ go build demo.go

I loaded the chinese font and set it to style.Font, display only widgets (e.g. Label, ButtonText, etc...) works fine, but TextEditor seems doesn't support do neither display or input Chinese characters.

I set the flags of TextEditor to nucular.EditField.

For input, after I switched my system input method to Chinese PinYin, every key strokes will input directly as English character.

For copy-paste, all Chinese characters will be shown as square like below.

Here shows how it looks like:

My OS is MacOS v10.15.1, go version 1.13.4, nucular is latest from main branch.

It's a great project. But I can't input any Chinese in linux/x11.

I tried both the gio and shiny backend,but neither of them supports linux/x11 input method,so there is no way to input Chinese.

Glfw implements these functions, and projects such as Fyne and giu are also in use, so is it possible to add a glfw implementation?

If you can't add a glfw implementation, can you tell me how to add a new implementation? I am familiar with the go language, but I am not familiar with this project, so it is a little difficult for me to implement this

func (ctr *rowConstructor) Static(width ...int) {
	for i := range width {
		width[i] = ctr.win.ctx.scale(width[i])
	}
...

If called with slice - this slice is modified.

This leads to bug - values scales on each call.

Just one simple question, is there an existing way to center the master window in screen?

If the answer is no, I may need to tweak the shiny/driver layer to archive it.

I'm digging GUI framework for go recently. From imgui->imgui-go->nuklear->golang-ui/nuklear all the way down to nucular. I think I just found the one I'm looking for!

Thanks for your effort. It's a really good job!

I can't appear to find any toggle or flag which may disable resizing on the MasterWindow

Viewing the overview example, it appears that the nucular.WindowScalable flag should disable resizing but it does not seem to affect the MasterWindow
