    When the html file that are used In the qhelpgenerator contain a reference to a svg file the content of this file is not show (in the assistant), contrary png files that are shown.
    The svg file is available and having it or not having it in the <files> section doesn't make a difference.

    How can I make a svg file visible?

      Hi and welcome to devnet,

      Try adding the svg module to your project.

        Thanks for the answer. I'm not really familiar with the qhelpgenerator / assistant, so with the "Try adding the svg module to your project." is a bit vague to me.
        The question where do I add what?
        is it possible to get an image showing what to do?
        is it a setting in for the qhelpgenerator or the assistant?

          See here for the Qt SVG module.

            Isn't this for using in code that uses Qt?
            I need it for the qhelpgenerator / assistant.

              The SVG support comes with it, so just try it to check whether it allows the SVG to be loaded.

                @SGaist said in SVG file in qhelpgenerator / assistant:

                check whether it allows the SVG to be loaded.

                the question is how can I check this?

                The small project I used:

                The index.qhp file:

                <?xml version="1.0" encoding="UTF-8"?>
                <QtHelpProject version="1.0">
                  <namespace>org.doxygen.Project</namespace>
                  <virtualFolder>doc</virtualFolder>
                  <filterSection>
                    <filterAttribute>doxygen</filterAttribute>
                    <toc>
                      <section title="My Project" ref="index.html">
                        <section title="Main" ref="index.html">
                        </section>
                      </section>
                    </toc>
                    <keywords>
                    </keywords>
                    <files>
                      <file>aa.svg</file>
                      <file>index.html</file>
                    </files>
                  </filterSection>
                </QtHelpProject>
                

                the index.html

                <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
                <html xmlns="http://www.w3.org/1999/xhtml">
                <head>
                <meta http-equiv="Content-Type" content="text/xhtml;charset=UTF-8"/>
                <meta http-equiv="X-UA-Compatible" content="IE=11"/>
                <meta name="viewport" content="width=device-width, initial-scale=1"/>
                <title>My Project: Main</title>
                <link href="tabs.css" rel="stylesheet" type="text/css"/>
                </head>
                <body>
                Generated <img src="aa.svg" alt="default"/>
                </body>
                </html>
                

                The aa.svg:

                <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
                <html xmlns="http://www.w3.org/1999/xhtml">
                <head>
                <meta http-equiv="Content-Type" content="text/xhtml;charset=UTF-8"/>
                <meta http-equiv="X-UA-Compatible" content="IE=11"/>
                <meta name="viewport" content="width=device-width, initial-scale=1"/>
                <title>My Project: Main</title>
                <link href="tabs.css" rel="stylesheet" type="text/css"/>
                </head>
                <body>
                Generated <img src="aa.svg" alt="default"/>
                </body>
                </html>
                

                The used commands:

                D:\Qt\qt-everywhere-src-5.14.0\install_nmake_2017_64\bin\qhelpgenerator.exe index.qhp -o "My Project.qch"
                D:\Qt\qt-everywhere-src-5.14.0\install_nmake_2017_64\bin\assistant.exe
                

                The result is in the assistant:

                61e6c30c-3292-4e66-abbe-dda12df43da8-image.png

                so we can see that the image is not displayed, the image should look like:

                fd7c5049-b888-4d39-9c93-4cd622584744-image.png

                  Just to be sure, if you use a .png, does it work ?

                    The png file: aa.png

                    The result:

                      Can you show the qdoc configuration file you are using ?

                        I don't have a qdoc configuration file or maybe there is one in the Qt tree that I'm not aware of.
                        Note that I'm not creating the qhp file through a Qt program but it is created by means of another program (doxygen)

                          By the way, which version of Qt are you using ?

                            As a reference the used configure line:

                              I just tried with the version 5.15.2 but still no svg file shown (in other words same result as with 5.14.0)

                                  Is there a quick possibility to get the qhelpgenerator and the assistant (for 5.15.2 or another version)?
                                  I found hhttps://www.qt.io/download-open-source but it looks like to take ages...
                                  (I'll try to keep downloading ...)

                                  Edit: The fact that it took "ages" was because I used everything of the 5.15.2 version, not just the e.g. msvc2019_64 part.This give quite a reduction in used disk space (and in installation time, though for just 2 needed executables it still is quite long).

                                    I installed the 5.15.2 version and found the

                                    D:\Qt\5.15.2\5.15.2\mingw81_32\bin\qhelpgenerator.exe
                                    D:\Qt\5.15.2\5.15.2\mingw81_64\bin\qhelpgenerator.exe
                                    D:\Qt\5.15.2\5.15.2\msvc2015_64\bin\qhelpgenerator.exe
                                    D:\Qt\5.15.2\5.15.2\msvc2019\bin\qhelpgenerator.exe
                                    D:\Qt\5.15.2\5.15.2\msvc2019_64\bin\qhelpgenerator.exe
                                    

                                    and

                                    D:\Qt\5.15.2\5.15.2\mingw81_32\bin\assistant.exe
                                    D:\Qt\5.15.2\5.15.2\mingw81_64\bin\assistant.exe
                                    D:\Qt\5.15.2\5.15.2\msvc2015_64\bin\assistant.exe
                                    D:\Qt\5.15.2\5.15.2\msvc2019\bin\assistant.exe
                                    D:\Qt\5.15.2\5.15.2\msvc2019_64\bin\assistant.exe
                                    

                                    I used the msvc2019_64 version and this does work (I also tried msvc2015_64a and this works as well) .

                                    It is still very interesting to know why my own build didn't work, so I can build my own version when necessary.

                                      I am experiencing the same issue. The SVG file is created by doxygen + qhelpgenerator, and then imported into QtCreator via Options, Help, Add qch file.

                                      When pressing F1 on a function, it opens the help, but the dependency graphs (svg) are not properly shown in QtCreator 5.0 with Ubuntu19. Should I maybe open a bug report?

                                        Sorry I lost track of this one.

                                        Yes you can. Even better if you can provide a minimal set of files and instructions to trigger this on the bug report.
