XDG-Shell:如何更改窗口大小?

我将xdg-shell v5添加到app以绘制窗口。当我发送set_fullscreen或set_maximize命令时,我看到在configure事件中正确设置了窗口状态和正确的大小,但没有任何结果。

我的配置事件功能:

    static void
xdg_surface_handle_configure(void *data,
              struct xdg_surface *xdg_surface,
              int32_t width,
              int32_t height,
              struct wl_array *states,
              uint32_t serial) {
    printf("Configure event got, width: %d, height: %d\n", width, height);
    VirtIOGPU *g = (VirtIOGPU*) data;

    g->window_state.activated = g->window_state.fullscreen =
    g->window_state.maximized = g->window_state.resizing = false;

    uint32_t *state;
    wl_array_for_each(state, states) {
        if(*state == XDG_SURFACE_STATE_MAXIMIZED) {
            printf("Surface state: XDG_SURFACE_STATE_MAXIMIZED\n");
            g->window_state.maximized = true;
        } else if(*state == XDG_SURFACE_STATE_FULLSCREEN) {
            printf("Surface state: XDG_SURFACE_STATE_FULLSCREEN\n");
            g->window_state.fullscreen = true;
        } else if(*state == XDG_SURFACE_STATE_RESIZING) {
            printf("Surface state: XDG_SURFACE_STATE_RESIZING\n");
            g->window_state.resizing = true;
        } else if(*state == XDG_SURFACE_STATE_ACTIVATED) {
            printf("Surface state: XDG_SURFACE_STATE_ACTIVATED\n");
            g->window_state.activated = true;
        }
    }

    if (width > 0 && height > 0) {
        g->prev_width = g->width;
        g->prev_height = g->height;
        g->width = width;
        g->height = height;
    } else {
        g->width = g->prev_width;
        g->height = g->prev_height;
    }

    xdg_surface_ack_configure(xdg_surface, serial);

    wl_surface_damage(g->surface, 0, 0, g->width, g->height);
    wl_surface_commit(g->surface);
    wl_display_dispatch_pending(g->display);
    wl_display_flush(g->display);
}

那么,在发送set_maximized之后如何查看最大化窗口? 是否可以以编程方式最小化窗口(现在通过Super + Tab)?

您的客户可能需要附加并提交具有正确尺寸的新缓冲区到表面。合成器完成了它应该做的所有事情,并期望你的客户调整大小。
