Don't Expand Window

[markwbennett]

Is there a way (in Amethyst settings or MacOS 14.5) to not expand a window beyond, for example, half the screen width. That is, I have two windows open side by side in Two Pane, and I close the right-hand window. The other is suddenly the full screen width; I'd like to leave the left-hand window at half the screen width.

Thanks!

Solved this. Took the 70-30 custom layout that someone posted it here, and converted it to 50-50, which I use instead of two-pane. Windows on the right are stacked horizontally.

/**
 * Divides the screen into a main mainPaneWidth pane and a secondary pane which will get divided horizontally by all remaining windows.
 * @returns {{initialState: {mainPaneCount: number}, name: string, getFrameAssignments: (function(*, *, *): *)}}
 */
function layout()
{
    return {
        name: "65-45",
        initialState: {
            mainPaneCount: 1
        },
        getFrameAssignments: (windows, screenFrame, state) => {
            const mainPaneCount = Math.min(state.mainPaneCount, windows.length); // Is state.mainPaneCount ever > 1?
            const secondaryPaneCount = Math.max(windows.length - mainPaneCount, 0);
            const hasSecondaryPane = secondaryPaneCount > 0;
            const mainPaneWidthRatio = 0.5 // ratio of main window to screen width
            const mainPaneWidth = screenFrame.width * mainPaneWidthRatio - screenFrame.x // screenFrame.width appears to be the width including the left margin (which is screenFrame.x), so we narrow the main pane by that amount.
            const secondaryPaneWidth = screenFrame.width - mainPaneWidth // screenFrame.width appears not to include the right margin, so our secondary pane widht is the full width minus the main pane width.

            const mainPaneWindowHeight = screenFrame.height;
            const secondaryPaneWindowHeight = hasSecondaryPane ? (screenFrame.height / secondaryPaneCount) : 0;

            let rep = 0; //number of repetitions in secondary frame.

            return windows.reduce((frames, window, index) => {
                const isMain = index < mainPaneCount;
                let frame;

                if (isMain) {
                    frame = {
                        x: screenFrame.x,
                        y: screenFrame.y + ((mainPaneWindowHeight/mainPaneCount) * index),
                        width: mainPaneWidth, //main pane is mainPaneWidth times the width of screen.
                        height: mainPaneWindowHeight / mainPaneCount
                    };
                } else {
                    frame = {
                        x: mainPaneWidth + screenFrame.x,
                        y: screenFrame.y + ((screenFrame.height / secondaryPaneCount) * rep),
                        width: secondaryPaneWidth, //secondary pane is rest of the width of screen
                        height: (screenFrame.height / secondaryPaneCount)
                    }
                    rep += 1;
                }
                return { ...frames, [window.id]: frame };
            }, {});
        }
    };
