Disabling context menu in UniURLFrame

[Rav]

Hello,

I have a simple HTML file (report) and want to show it to the user. For this purpose I use TUniURLFrame in a way like this:

uniURLFrame.HTML.LoadFromFile('c:\1.html');

It works perfect except that the browser context menu in uniURLFrame still works regardless of the boDisableMouseRightClick option in UniMainModule.BrowserOptions. It wouldn't have been a large problem but all browsers have the "Save as" option which works dreadful - the saved file is absolute nonsense.

Is it possible to disable the context menu in UniURLFrame or is there another better way of showing the prepared HTML file?

Hi,

 

If the "iframe" is in a same domain, for now you can try like this:

 

UniURLFrame1->ClientEvents->ExtEvents ... frameload fn:

function frameload(sender, frame, eOpts)
{
  sender.hideMask();
  sender.iframe.contentWindow.oncontextmenu = function(){
    return false
  }
}

Best regards.

[Rav]

Thanks, but didn't work - the context menu appears as before.

Hi,

 

Can you try this ?!:

function frameload(sender, frame, eOpts)
{
  sender.hideMask();
  sender.iframe.contentWindow.window.oncontextmenu = function(){
    return false
  }
}

Best regards.

Yes, sure.

I have just tested UniFrame demo - your code disables the context menu when it's empty. If you go to any URL or load HTML file - the menu appears again.

Maybe your code should be placed whenever UniFrame is changed? I will test it right now...

No it doesn't work either

      FUniUrlFrame := TUniURLFrame.Create(TabSheetNew);
      FUniUrlFrame.Name := Name + '_frame';

      FUniUrlFrame.Parent := TabSheetNew;
      FUniUrlFrame.Align := alClient;

      FUniUrlFrame.OnFrameLoaded := UNIFRAME_LOADED;
      FUniUrlFrame.ScreenMask.Target := FUniUrlFrame;
      FUniUrlFrame.ScreenMask.Enabled := true;
      FUniUrlFrame.URL := report_url;

   

   FUniUrlFrame.ClientEvents.ExtEvents.Add('frameload(sender, frame, eOpts){  sender.iframe.contentWindow.window.oncontextmenu = function(){return false}}');

If you don't have access to the iframe's contents, in your case I suppose that's what it is, then it is not possible.

Sorry, it's not possible if it's on an external domain.

[donlego]

actually a local url, just make a test if it's an external domain for tes the funcion

   FUniUrlFrame.ClientEvents.ExtEvents.Add('frameload = function frameload(sender, frame, eOpts){  sender.iframe.contentWindow.window.oncontextmenu = function(){return false}}');

Sorry, maybe I misunderstand your case, if you are using a local url, then this should work as expected...

But in your case, you open a different domain in the frame.

localhost site

Does it work as expected for FF?
