UG自定义右键弹出菜单和快捷键UG的右键弹出菜单包含了一些我们常用的功能，比如Roate、Fit等，为了使用的更加方便，我们也可以自己打造！打开UG安装目录下的UGII下的menus文件夹，里面包含了一些*.men和*.tbr，我们以文本方式打开它，发现也不难理解。例如，我们想在右键弹出菜单里面的roate和pan之间加入如图示的view下的orient功能，首先我们打开ug_main.men,查找orient，会看到下面的 BUTTON UG_VIEW_REFRESHLABEL &RefreshBITMAP refresh_window.bmpACCELERATOR F5ACTIONS STANDARDCASCADE_BUTTON UG_VIEW_EDITLABEL O&perationBUTTON UG_VIEW_ORIENTLABEL Ori&ent...ACTIONS STANDARD参考上面部分我们会看出快捷键的定义是*ACCELERATOR来指定的，我们把红色部分即BUTTON UG_VIEW_ORIENT的LABEL下面加入一行ACCELERATOR Ctrl+Alt+O(这里可以自行定义，但不要和别的重复)，保存，这样我们就把快捷键定义好了，然后我们选中红色部分复制。接着打开ug_view_popup.men，它就是右键弹出菜单的定义文件。为了把它放在roate和pan之间，我们把刚才复制的部分粘贴在下面图示的位置：TOGGLE_BUTTON UG_VIEW_POPUP_ROTATELABEL R&otateBITMAP rotate.bmpACCELERATOR F7ACTIONS STANDARDBUTTON UG_VIEW_ORIENTLABEL Ori&ent...ACCELERATOR Ctrl+Alt+OACTIONS STANDARDTOGGLE_BUTTON UG_VIEW_POPUP_PANLABEL &Pan BITMAP pan.bmpACCELERATOR F9ACTIONS STANDARD
