Unable to size window dimensions with setSize

[alecstein]

For a minimal repro, try this:

zig-webui/src/examples/call_js_from_zig

pub fn main() !void {
    var nwin = webui.newWindow();

    _ = nwin.setSize(10, 10);     // try resize before show

    _ = nwin.show(html);

   _ = nwin.setSize(10, 10);     // resize after .show

    _ = nwin.bind("MyButton1", my_function_count);
    _ = nwin.bind("MyButton2", my_function_exit);

    webui.wait();


    webui.clean();
}

In neither case does nwin.setSize(...) actually change the window size.

I'm not sure if this is a bug with this library (which essentially wraps WebUI) or with WebUI itself, but I'm posting it here just in case.

I tested it using the C example, and it's working for me. We should use the debug version of WebUI to see what's going on in the logs.

On the other hand, WebUI only passes the window size using the command line if the web browser supports it. Otherwise, WebUI simply runs window.resizeTo(x, y);, so I suggest you use window.resizeTo in your UI using JavaScript while we debug the Zig wrapper.

@hassandraga Honestly it might be browser related. After window.resizeTo failed even in the console, I found this discussion:

Apparently you're (in many cases) only allowed to modify windows the size of windows opened with window.open(), as a security measure.

When you say it's working, what browser did you try it on? I'm using Firefox on MacOS Monterey.

I test it using Chrome in Linux.

em.. linux chrome is available with zig

[jinzhongjia]

I will still test it using other browser.
To be honest, this function doesn't even do wrapping, it just converts the integer type

[jinzhongjia]

weird, zig setsize is not available with firefox
@hassandraga maye we should test it with C on firefox

[jinzhongjia]

I have test it with C on firefox, it really doesn't work

[jinzhongjia]

I will open an new issue in webui repository.

The WebUIFirefoxProfile folder was already deleted in my system, so webui_set_size() worked when I test it. But starting from the second run, Firefox remember the last manually changed size and position, so it ignores the values setting by WebUI command lines.

A quick workaround is by deleting the Firefox profile on exist:

webui.deleteAllProfiles(); /// Delete all window object's web-browser profiles
webui.clean(); /// Clean all memory resources

Let's then figure out a better solution for Firefox in webui-dev/webui#296.
