Here is updated sample <style> body {padding: 20px} td {height: 20px; resize: horizontal; } .gauge1 {background: linear-gradient(to bottom, steelblue, blue);} .gauge2 {background: linear-gradient(to bottom, lightgreen, green);} #main > tbody > tr > td:first-child {border-right: solid red 2px} </style> <table width="800" id="main"> <tr> <td width="50%"> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"></td> </tr> </table> </td> <td> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"><div style="position:relative; left:calc(100%+10)">Row 1 name</div></td> </tr> </table> </td> </tr> <tr> <td> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"></td> </tr> </table> </td> <td> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"><div style="position:relative; left:calc(100%+10)">Row 2 name</div></td> </tr> </table> </td> </tr> </table> -

I've sent you library update with new event OnShowResizeHint. Please override this method to hide hint or draw custom hint. -

Alexander Sviridenkov replied to wuwuxin's topic in VCL
1. Resize hint is fixed. Any element can have normal hint (using title attribute or HTML hint using data--hint attribute, see HCL main demo) but on mouse hover. 2, Vertical bar within table can be added by setting border-right for first cells of outer table, larger bar can be added as absoulte positioned element 3. Row name behind table right border can be added as relatively positioned text for last cells -

Alexander Sviridenkov replied to wuwuxin's topic in VCL
Yes, f.e. you can give ID to each cell and use something like Caption := FormatFloat('0.0', HtPanel1.Doc.GetElementbyId('cell1').InnerWidth) Also HtPanel has event OnElementResizeEnd where Sender is sized element. -

Zero lines of Delphi code, just one HtPanel: (artefacts on video are from GIF compression) HTML: <style> body {padding: 20px} td {height: 20px; resize: horizontal} .gauge1 {background: linear-gradient(to bottom, steelblue, blue);} .gauge2 {background: linear-gradient(to bottom, lightgreen, green);} </style> <table width="800"> <tr> <td width="50%"> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"></td> </tr> </table> </td> <td> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"></td> </tr> </table> </td> </tr> <tr> <td> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"></td> </tr> </table> </td> <td> <table width="100%"> <tr> <td class="gauge1" width="70%"></td> <td class="gauge2"></td> </tr> </table> </td> </tr> </table> -

Dangerous bug in 10.4.2 / Android32 compiler (not sure about 64). a, b : single a is unitialized (= -nan in debugger), b = some value, f.e. 100.5; if a <> b then <code>, <code> is not executed. ASM code: if fValue <> aValue then C5CCAD8C ED9D1A02 vldr s2, [sp, #8] C5CCAD90 EEF70AC1 vcvt.f64.f32 d16, s2 C5CCAD94 ED901A00 vldr s2, [r0] C5CCAD98 EEF71AC1 vcvt.f64.f32 d17, s2 C5CCAD9C EEF41BE0 vcmpe.f64 d17, d16 C5CCADA0 EEF1FA10 vmrs APSR_nzcv, fpscr C5CCADA4 9001 str r0, [sp, #4] C5CCADA6 ED8D0A00 vstr s0, [sp] C5CCADAA D027 beq.n 0xc5ccadfc <Htmlcss.TMeasure.SetValue(float)+124> C5CCADAC D626 bvs.n 0xc5ccadfc <Htmlcss.TMeasure.SetValue(float)+124> C5CCADAE E7FF b.n 0xc5ccadb0 <Htmlcss.TMeasure.SetValue(float)+48>

Video made for Delphi Showcase. Both, desktop application and server software (for cloud access) are made in Delphi, nothing external except OCR dll. Windows, Mac and Linux versions. All UI is created in HtPanels (HTML Library), document conversion is performed by Office library. Support for custom fonts and letter spacing was added to FMX canvas (currently only for windows), without this PDF documents cannot be rendered properly. https://www.youtube.com/watch?v=PdudQwjhCJg

@Attila Kovacs thak you. There is also Calendar sample application in /Sample Projects/ folder.

Looks like there is bug in 10.3 Linux compiler: maximum enum size is limited to 8 bytes. F.e. type TMyEnum = (a1, a2, ..a100); TMyEnums = set of TMyEnum; var X: TMyEnums; sizeof(X) returns 8 on Linux platform.

Linux: wrong enum size
Alexander Sviridenkov replied to Alexander Sviridenkov's topic in RTL and Delphi Object Pascal
How mininum enume size may affect this case? This test enum is larger than maximum setting for "Minimum enum size" parameter. -
Linux: wrong enum size
Alexander Sviridenkov replied to Alexander Sviridenkov's topic in RTL and Delphi Object Pascal
Another test: if e191 in LargeEnumSet then Writeln('YES'); No YES in output. -
Linux: wrong enum size
Alexander Sviridenkov replied to Alexander Sviridenkov's topic in RTL and Delphi Object Pascal
Output is the same, but in debugger Evaluate/Modify window Sizeof(LargeEnumSet) shows 8. Sizeof(LargeEnumSet) is calculated at compile time, in asm code there is explicit $19 -

One more bridge between desktop and web: HTML Office Library. The first Delphi library for reading all office formats (+ PDF) and convert them to plain HTML on the fly. Converted document contains only plain HTML/CSS/SVG and can be displayed using HTML Component Library or browser. Library provides a uniform access to an entire document and its parts, document resources (fonts, images, etc) and properties (title, Table of Contents, etc). The library doesn't depend on any external components (DLLs, OLE, ActiveX, etc) and is cross-platform. Fully written in Delphi and comes with full source code. Following document formats are supported: Rich Text Format (RTF) MS Word 6-2007 binary format (DOC) MS Word XML document (DOCX) MS Power Point binary format (PPT) MS Power Point XML format (PPTX) MS Excel binary format (XLS) MS Excel XML format (XLSX) Adobe PDF format (PDF) Supercalc format (SXC) EPUB (electronic books). Besides the document conversion classes it also contains the following: EMF/WMF to SVG conversion TTF to WOFF conversion TTF normalization TTF to SVG conversion CFF to TTF conversion Adobe PostScript to TTF conversion. Supported Delphi versions are Delphi XE2 - Delphi 10.4.1. Supported platforms: Windows 32/64 VCL and FMX, MacOS, Linux. There are two compiled demos available https://delphihtmlcomponents.com/FileBrowser.zip 1. Simple document viewer: allows to view any document on hard drive using file tree on left side and HtPanel on right. To view final HTML press View in browser button. No installation required. 2. Document Indexer: create full text search index for documents located in selected folders and find any document from application or Web. No installation required. How to use: Run application (OfficeIndex.exe). Click Add folder and select folder containing office documents. Click Start indexing, wait until it completed. Search for documents using one of the following: a) Go to Search tab and enter search query (any words). b) Click Web interface and enter search query. c) Point mobile phone camera (mobile should be connected to the same router) to QR code and open mobile interface. Full cource code of both applications are included in library.

ANN: HTML Office Library

Thank you. I'll think about this. -
ANN: HTML Office Library
Alexander Sviridenkov replied to Alexander Sviridenkov's topic in Delphi Third-Party
Yes. Competitors price (not Delphi because there is no similar library for Delphi) is $15K-$50K Developing somethign similar yourself will cost at least $100K. So $2k (with discount) for site license is quite low price. -

This quote if for HtmlViewer project. HTML Component Library supports almost all HTML tags and CSS properties on all platforms (including mobiles) for all Delphi versions from Delphi 5. Works on all Windows versions starting from XP, has no external dependencies, is more safe (JS is not executed) and gives you full control on loading external files (images, stylesheets, etc). Also it can be used for rendering HTML in any other control (trees, grids, etc) and another libraries (FastReport, ReportBuilder, etc) using GDI, GDI+, DirectX. plaint text or custom renderer.- 19 replies
