I need to change the componentCls of the grids actionbuttons

1) if I want to change componentCls in all the application I modify do I have to do to my CustomCSS ?

If you want to use a button to go to a specific page

 

procedure TMainForm.bSetPageClick(Sender: TObject);
begin
    UniSession.AddJS (pdfFrame.JSName + '.iframe.contentWindow.PDFViewerApplication.page=' +  IntToStr(UniSpinPage.Value));
end;

In the close form or destroy you have insert

where uHTMLPDF is your TUniPDFFrame ?

[Survey: Features you want to see in 2021]

1. in the editor 

ExtEvents and UniEvents highlighted if code present inside (without having to enter each element to see if we have activated any code).

 

2. building the user interface takes 60% of the time of building an application. 

You would need an editor with the ability to choose values like to

x-panel-header-default

x-panel-body-default

etc..

to generate custom css or  an easier way to manipulate a new application theme

 

3. a solution for custom screen mask without using EnableSynchroniusOperations passing, for example, an gif and a provedure to execute.

SynchronousOperations is not a good practice

I agree but esiet a problem when we have to use long processes and signal the user to wait via hourglass ...

[UniPDFFrame modify rotation button]

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
