Question: How to set position to the center of the screen?

[Aukstkalnis]

Hi. I want to set window to the center of my screen. How do I do it? There is no current method to get total of the current screen and there is no method to set in directly to the center. I only have SetPosition method.

I am using Go programing language and fedora 39 OS.

mayebe you can use js api screen.width screen.height or screen.availWidth or screen.availHeight to get screent size
then you can get browser size
Then we can get x and y after a small amount of calculations
This is just a solution I proposed, I have not tested whether it is feasible

Try this:

function centerWindow() {
    const screenWidth = screen.width;
    const screenHeight = screen.height;
    const width = window.outerWidth;
    const height = window.outerHeight;
    const centerX = (screenWidth - width) / 2;
    const centerY = (screenHeight - height) / 2;
    window.moveTo(centerX, centerY);
}

centerWindow();

It kinda works but I can see the change in position. I guess we can close this issue, but can be feature for the future to implement functions get position, monitor size, mult-imonitor positioning. etc.. Anyway, thanks :)

webui is not like the other GUI libraries, a webui window is a web browser window, so just let the browser handle the size and position. If you still want to to get the current window info just use JavaScript, example run JS from your backend:

"return window.outerWidth;"
"return window.outerHeight;"

/**
 * @brief Centers the window on the screen. Works better with 
 * WebView. Call this function before `webui_show()` for better results.
 *
 * @param window The window number
 *
 * @example webui_set_center(myWindow);
 */

void webui_set_center(size_t window);
