问题描述
我如何在 autodesk forge 查看器上禁用右键单击事件。我想隐藏上下文菜单。有人知道这个吗？
解决方法
如果您想隐藏上下文菜单，请使用：
viewer.contextMenu.hide();
如果您想删除上下文菜单项，并添加您自己的上下文菜单，请使用：
您可以通过 this.viewer.unregisterContextMenuCallback('Autodesk.Dasher.ContextMenuExtension'); 删除默认的 Autodesk Forge Viewer 上下文菜单
您可以通过
this.viewer.registerContextMenuCallback('Autodesk.Dasher.ContextMenuExtension',(menu,status) => {}
参考：HOW TO ADD CUSTOM CONTEXT IN FORGE VIEWER。 这是用于在 Forge Viewer 中删除和添加您自己的自定义上下文菜单的示例类：
export default class ContextMenuExtension extends Autodesk.Viewing.Extension {
constructor(viewer: Autodesk.Viewing.Private.GuiViewer3D,options: any) {
super(viewer,options);
}
load(): boolean {
console.log('ContextMenuExtension loaded');
let self = this;
this.viewer.registerContextMenuCallback(
'Autodesk.Dasher.ContextMenuExtension',status) => {
// Remove all existing menu items
while (menu.length > 0) {
menu.pop();
}
// Add our new item if an object is selected
if (status.hasSelected) {
menu.push({
title: 'Send to HoloLens',target: function(): void {
let messageSpecs = {
'msgTitleKey': 'Sent to HoloLens','messageKey': 'Sent to HoloLens','messageDefaultValue': 'This object has been sent to HoloLens for viewing.',};
Autodesk.Viewing.Private.HudMessage.displayMessage(
self.viewer.container,messageSpecs
);
setTimeout(
() => {
Autodesk.Viewing.Private.HudMessage.dismiss();
},10000
);
},});
}
}
);
return true;
}
unload(): boolean {
console.log('ContextMenuExtension unloaded');
this.viewer.unregisterContextMenuCallback('Autodesk.Dasher.ContextMenuExtension');
return true;
}
}
如果您只想禁用上下文菜单，只需将 setContextMenu 方法设置为 null。
viewer.setContextMenu(null);
如果您想再次显示上下文菜单，只需保留上下文并进行设置即可。
// you need to get current context menu before calling setsetContextMenu(null)
var contextMenu = viewer.contextmenu;
viewer.setContextMenu(null);
....
//set preserved contextMenu inf you want to show it again.
viewer.setContextMenu(contextMenu);
