Get selected text from UniURLFrame

[Isabelle]

Hi,

I'm using Unigui for the first time and I find it great.

In UniURLFrame a PDF file is displayed. I want to copy selected text with mouse to a UniEdit.

Is it possible to do this?

Thanks for your help.

Hello,

Thank you for your interest in uniGUI.

For what purpose? And if it is copy-protected (although I'm not sure)?

Hi Sherzod,

Thank you for reply.

I want to copy the word selected with the mouse (after releasing the left mouse button) into a UniEdit. It's like you select a word with the mouse, then you do Ctrl + C and then you do Ctrl + V.

its like :

I want to get several words from the UniURLFrame and paste them directly to UniEdits

 

Thank you

Also try this approach:

procedure TMainForm.UniPDFFrame1FrameLoaded(Sender: TObject);
begin
  UniPDFFrame1.JSInterface.JSCode(#1'.getDoc().addEventListener("mouseup", function(){if ('#1'.getDoc().getSelection()){' + UniEdit1.JSName + '.setValue('#1'.getDoc().getSelection().getRangeAt(0).toString())}});')
end;

Error :

Permission Denied to access property "document" on cross-origin object :

O25.getDoc().addEventListener("mouseup", function(){if (O25.getDoc().getSelection()){O70.setValue(O25.getDoc().getSelection().getRangeAt(0).toString())}});

 

 

[Isabelle]

it works fine, thank you ! But, when I launch the application I get this error:

Permission Denied to access property "document" on cross-origin object :

O25.getDoc().addEventListener("mouseup", function(){if (O25.getDoc().getSelection()){O70.setValue(O25.getDoc().getSelection().getRangeAt(0).toString())}});

 

Is it possible to do this with several UniEdit: I have 10 UniEdit. I want to copy 10 words in each UniEdit please ?

Thank you

Please explain in more details.

[Isabelle]

in the Form, I added 10 UniEdit (UniEdit1, UniEdit2, UniEdit3,... UniEdit10).

I select 10 words with the mouse and each word must be copied into a UniEdit: example:

- I select the first word, then it will be copied into UniEdit1.

- I select the second word, then it will be copied into UniEdit2.

- I select the third word, then it will be copied into UniEdit3. ...

- I select the tenth word, then it will be copied into UniEdit10.

thanks

Are you selecting the text at one time?

[Isabelle]

no, one by one

Okay, then you need to modify the code above to send the selected text to the server (using ajaxRequest), and there you will think about the logic.

[Isabelle]

Ok, I don't know how to do this (using ajaxRequest).

Is it possible to set text selection area in UniPDFFrame? As is shown in the attached picture.

Framed areas are not fixed (areas of selected text can be anywhere in the PDF).

I know you have to define the text retrieval areas, with Unigui, I don't know how to do it, but under VCL yes, I have already done it.

Thank you for your help Sherzod !

 

[Sherzod]

Sorry, are you using trial edition? Which build?

How?

[Isabelle]

I use the latest version (trial).

    begin
      if SelectionEnd < SelectionStart then
        Text := Pdf.Text(SelectionEnd, SelectionStart - SelectionEnd + 1)
      else
        Text := Pdf.Text(SelectionStart, SelectionEnd - SelectionStart + 1);

      Clipboard.AsText := Text;

Seems there is no code of what you asked above:

ok.

Before getting text, you have to define the selection areas with a Shape (as in the picture). After that, I have the coordinates of the Shape (Top, Height, width and left), and finally i can get the selected text (which is framed by the Shape):

Edit8.Text := coordonates

It is possible to do it with Unigui ?

Thank you

[Sherzod]

I do not promise that I can do something, but in any case, could you make a testcase (maybe an exe) on VCL to understand your case completely?

[Isabelle]

Hi,

what I want is explained in the attached photo. The colored frames are TShape (in VCL).

Text copied into TEdit is based on: Top, Left, Widht, Height of a TShape. TShape areas are user defined.

Thank Sherzod 🙂

Hello,

Sorry, I don't think this is possible with pdfviewer...

Hi Sherzod,

Thank you.

Yes, I know it's not possible with PDFView: I tested it before asking my question on this forum. PDfView is incompatible with Unigui (for VCL and FMX usage).

My question was is it possible to do the same with Unigui? In my opinion, yes, it can be done with JavaScript, but how?

The trick is to have : get X,Y co-ordinates of the selected Text area from PDF.

Thank you.

[Sherzod]

Hi,

I don't think there is an easy solution, if you can access the content of the pdf then maybe using styles.

Because if you use UniHTMLMemo, then yes there you can use styles to do this.

[Isabelle]

Can a PDF file be displayed in the "UniHTMLMemo" component?

Is it possible to have coordinates of selected text in UniPdfFrame?

thank you

Sorry, I didn't mean to display pdf in UniHTMLMemo.

What will it give you? Keep in mind that there is still the possibility of scaling, scrolling...

[Isabelle]

Hi Sherzod,

Thank you.

yes, I take into account the scaling (zoom). Suppose the PDF file is scaled to 100%. We need to have the coordinates of the text capture areas (Top, Height, Left, Widht).

I thought of putting a UniPanel (on the text to have) UniPDFFrame to have its coordinates. What do you think of that?

Thank you
