I use DEVART Unidac with Delphi Sidney See https://www.devart.com/unidac/compatibility.html for compatibily version

procedure TfForm1.UniPDFFrame1Loaded(Sender: TObject); begin if UniPDFFrame1.PDFURL > '' then begin // download button UniSession.AddJS (UniPDFFrame1.JSName + '.iframe.contentWindow.document.' + 'getElementById ("download").style.display = "none"'); UniSession.AddJS (UniPDFFrame1.JSName + '.iframe.contentWindow.document.' + 'getElementById ("secondaryDownload").style.display = "none"'); end; end;

I try with my iPhone IOS 14.5.1 http://prime.fmsoft.net/demo/touch/mdemo.dll/m it works fine.

try https://www.gyrocode.com/articles/how-to-increase-print-quality-of-pdf-file-with-pdf-js-viewer/

/* UniDbGrid readonly CheckBoxes NOT grayed */ .x-item-disabled .x-grid-checkcolumn { opacity: 1 !important; }

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 ? 2) I tried to change the value on a single grid by removing the hint values of the action button and inserting The program does not give any errors, it displays the message correctly but does not apply the componentCls.

or UniSession.AddJS (pdfFrame.JSName + '.iframe.contentWindow.document.' + 'getElementById ("print").click()');

procedure TMainForm.bPrintPDFClick(Sender: TObject); begin MainForm.pdfFrame.JSInterface.JSCall('iframe.contentWindow.print', []); end;

Sorry but I only use only and always Delphi (for thirty years ...) and I don't know C ++ anyway in Delphi First Page UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("firstPage").click()'); Last page UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("lastPage").click()'); Next page UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("next").click()'); Previous Page UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("previous").click()'); i used unigui for a document solution Angelo

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 // Clear PDF uHTMLPDF.PDFURL := ''; where uHTMLPDF is your TUniPDFFrame ? I have a document application that uses a lot of PDFs and I have no problems with either chome or Edge Angelo

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. Of the series shows the animated git until the procedure has not finished

if I use a theme other than classic I have the borders in the edit boxes as shown in the figure. how can i hide them with css?

obviously in on FrameReady or FormShow begin UniSession.AddJS('MainForm.form.mask("Action in progress ...")'); .OnThreadCreateReport.Enabled := True; end;

One solution is to use a ThreadTimer (RunOnce ...) on FrameReady or FormShow begin UniSession.AddJS('MainForm.form.mask("Action in progress ...")'); end; procedure TfReporting.OnThreadCreateReportTimer(Sender: TObject); try // execute the long action finally UniSession.AddJS('MainForm.form.unmask()'); end; begin end;

UniMainModule -> BrowserOptions -> boDisableChromeRefresh = True

Wonderful idea !!! Angelo

Delphi 10.4.1 is here ! Embarcadero just released Delphi, C++ Builder and RAD Studio 10.4.1. https://blogs.embarcadero.com/rad-studio-10-4-1-has-been-released/

In newer versions of ExtJS, the filter does not work (as indicated in the forum) how can i dynamically load the items of a menu? UniGui Version 1.90.0.1534 Delphi Rio

Collapse UniSession.AddJS('Ext.onReady(function () {' + YourPanel.JSName + '.collapse()});'); expand UniSession.AddJS('Ext.onReady(function () {' + YourPanelJSName + '.expand()});');

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 ... When I have a long query or I have to download a file I have to report to the user the inability to act otherwise he thinks it is the locked system Angelo

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

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 Angelo

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
