最近,在ubuntu系统开发一个小软件,需要创建一个无标题的窗口。我使用的是xcb库(它对Xlib进行了封装),可惜一直没有找到方便的接口。于是搜索了一番之后,写成了这个函数: void xcb_hide_title_bar(xcb_connection_t *c, xcb_window_t window) { struct { ...
xcb_drawable_t window; uint32_t mask; uint32_t values[2]; /* Create a window */ window = xcb_generate_id (connection); mask = XCB_CW_BACK_PIXEL | XCB_CW_EVENT_MASK; values[0] = screen->white_pixel; values[1] = XCB_EVENT_MASK_BUTTON_PRESS; ...

QXcbConnection是一个XCB连接错误,错误代码为2。XCB是一个用于X Window系统的低级别通信协议库,它允许客户端应用程序与X服务器进行通信。当Qt安装程序在Docker容器中运行时,可能会遇到这个错误。 解决这个问题的方法是确保Docker容器中正确安装了XCB库和相关依赖项。可以通过在Dockerfile中添加以下命令来安装所需的...
