在wx.ToolBar中,我有一个CheckLabelTool,当鼠标单击时,我希望菜单直接在其下面弹出。我试图获取工具的位置以便设置菜单的位置,但是我尝试过的所有方法(如GetEventObject、GetPosition等)都只给我返回了工具栏的位置,所以菜单从工具栏下弹出,但是离相关工具很远。你有什么建议吗?如果有更好的选择,我需要该工具具备切换和位图功能,但我并不固定于CheckLabelTool。
谢谢!
谢谢!
您需要绑定到您的检查工具的EVT_MENU事件。一旦选中工具按钮,您可以弹出菜单。如果您不指定弹出窗口的位置,则会使用鼠标的当前位置,这正是您想要的。“在指定的坐标相对于此窗口时弹出给定的菜单,并在用户关闭菜单后返回控制。如果选择了菜单项,则将生成相应的菜单事件并像往常一样进行处理。如果给出默认位置,则将使用鼠标光标的当前位置。”
