XDG-Shell:如何更改窗口大小

Question

我将 xdg-shell v5 添加到应用程序中以绘制窗口。当我发送set_fullscreen或set_maximize命令时，我在配置事件中看到正确设置的窗口状态和正确的大小，但没有任何反应。

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: %dn", 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_MAXIMIZEDn");
            g->window_state.maximized = true;
        } else if(*state == XDG_SURFACE_STATE_FULLSCREEN) {
            printf("Surface state: XDG_SURFACE_STATE_FULLSCREENn");
            g->window_state.fullscreen = true;
        } else if(*state == XDG_SURFACE_STATE_RESIZING) {
            printf("Surface state: XDG_SURFACE_STATE_RESIZINGn");
            g->window_state.resizing = true;
        } else if(*state == XDG_SURFACE_STATE_ACTIVATED) {
            printf("Surface state: XDG_SURFACE_STATE_ACTIVATEDn");
            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，发送set_maximized后如何查看最大化的窗口？是否可以以编程方式取消最小化最小化窗口(现在通过 Super+Tab(？

客户端可能需要将具有正确尺寸的新缓冲区附加到图面。合成器已经完成了它应该做的所有事情，并期望你的客户端调整大小。
