UniPDFFrame modify rotation button

[azago]

I need to be able to rotate the images of a PDF inside the UniPDFFrame object

The problem is that the rotation buttons are on the inside the secondarytoolbar

1) Is it possible to rearrange the buttons so that the rotation buttons are at the same level as the zoom buttons (toolbarViewer) ?

alternatively

2) It is possible to send (using an external button) a command to UniPDFFrame to execute PageRotateCw or PageRotateCcw

or

3) It is possible to send a char 'r' o Shift-r (shortcut) to UniPDFFrame to execute rotation

In the letter case i tried generic delphi code 

 PostMessage(UniPDFFrame.Handle, WM_CHAR, Ord('r'), 0);

but non working

 

Thank's

Angelo

Hi

Please use this code:

  with UniPDFFrame1, JSInterface do
  begin
    JSCallDefer('iframe.contentWindow.document.getElementById("pageRotateCw").click',[], 500);
  end;

Thank's Page Rotate work.

I have an evolution on my software. I replaced the bar of pdf.js with a UniToolbar.

How to send a command from change the zoom, for example "page width" to current pdf ?

It's a selection and not working the click action.

 

Thank's

You can try this approach I think:

  UniPDFFrame1.JSInterface.JSCall('iframe.contentDocument.getElementById("zoomIn").click', []);

  UniPDFFrame1.JSInterface.JSCall('iframe.contentDocument.getElementById("zoomOut").click', []);

Sherzod,
in my application I have already linked the various buttons to the actions of the pdf.js

 

What I miss and what I would like to be able to do is associate
to these last 3 buttons the action of changing pdf scales

That is, they should execute the command as if the selection of

 

The question
How to associate the same action as the selection scaleSelect  change to a Unibutton ?

Thanks

Angelo
