I am developing a desktop application with Electron. I have added some items to the menu bar.
Sometimes I open some modal forms with bootstrap in the program. When these popups are open I want to disable the menu items.
I have made some research and some people says that the menu bar could be removed. But I do not want to create my own HTML menu.
And there is another option, maybe the best approach. Disabling all the options of each dropdown menu. Each menuitem has an enabled attribute, so it can be changed in runtime.
Is there way to avoid dropping down the menu and disable the drop-down menu?
Dynamic menus are not currently supported. This has something to do with the fact that the menus in Electron use the Chromium menu code which has no dynamic features.
When your File menu is empty, you could replace the entire menu with one that does not have the File menu in it?
I am trying to implement a context menu on a dijit tree, and the context menu should display different contents and enable/disable the menu items based on which tree node I right-clicked on. Basically what I need is a pre-processing function that gets called before the context menu is displayed where I can run some logic to determine which menu items to show/hide, enable/disable, etc. I feel like this is a very basic functionality for context menus but wasn't able to find the solution, so I'm asking people for help.
Any help would be appreciated. Thanks!
Dijit Tree has no built-in support for context menus, but you can use the Menu widget in conjunction with the Tree. The Menu widget is used for context menus, with right-click which can really suite your use-case.
Documentation and examples here:

Here I want to add my custom menu option i.e. ColorZilla, Aptana Studio on web browser right click
You can only do this with a browser plugin. Each browser will have its own syntax for plugins and specifically adding context menu items.
Aleks G. is right you cannot do that directly within the browser.
I don't know if it can help you or if it is what you are looking for but, within the browser you can handle the right click interaction in order to display your own custom menu ( not a particular menu item but the full menu ) ... meaning the default browser menu won't get displayed at all.
In case you are interested, you can have a small sample here
hii,I was just learning android i want create menu like this at this image This Menu
i was confused make this,anyody know how i can do it with 4 item like the link above ?
please help me.
sory if my language english bad.
To my knowledge custom menu and options menu can be modified (adding and removing menu items) easily.
If u want your own custom option menu, you may have to simulate by creating layouts.
1) Creative a layout and inflate the layout and show on clicking on the menu button.
2) If u want to occupy whole screen then better use Images and TextViews and create a new activity and launch the activity on clicking the options menu in OnCreateOptionsMenu().

I've a PyQt4 Installed on Python 2.6. I wish to insert actions or widgets into a toolbar in QtDesigner instead of adding them in code, with addAction or addWidget (as simple as adding actions to a menu in design time).
You can add actions by dragging them to your tool bar from the "Action editor" dock window. You cannot add widgets to the tool bar in Qt Designer, I'm afraid you'll have to do this from your code.
You can create your own widget plugins with new or extended functionalities.
Just follow the definition rules from the documentation .
I use a lot of custom widgets inside the Qt Designer.
Once you have figured out, how it works, it becomes a really power full method for your design work flow inside Qt Designer.
