Use SVG Icons with wxDataViewCtrl (and others)

[evstevemd]

Hi,
I want to replace my png icons with SVG ones. I have tried to google and I could not find any useful information so far. Have anyone tried that? How far does wxWidgets support it?

Thanks!

wxWidgets itself has no SVG reading support. There is http://wxsvg.sourceforge.net/ but unfortunately it requires Cairo under Windows, so that's not an option for me.

For simple SVGs you can use https://github.com/memononen/nanosvg
It's very easy to integrate as it only consists of two header files. But it only supports a part of the SVG standard, so some SVGs may look broken or imcomplete. Most of the Tango icons look fine though.

Thanks DM.
I will try nanosvg.
Cairo is a no-go for me too

Here is the source for my SVG_panel i used for testing nanosvg. Maybe it helps.

FYI:

If you use Msys2, you will see there are already some SVG library packages, you can easily install them by the pacman command:

Package: mingw-w64-x86_64-wxsvg - MSYS2 Packages

Package: mingw-w64-x86_64-librsvg - MSYS2 Packages

Once you install this package, all the appendices are also installed.

It looks like wxWigets are now using nanosvg.


Just FYI: wxWidgets does now include nanosvg as SVG renderer · Issue #201 · memononen/nanosvg

I try to use doublemax's svg_panel.cpp/h file to show a svg file.

While I see that nanosvg can not support showing the text field. Luckily, I found someone has a pull request to the nanosvg, and the parser can extract the text, and I can now draw the text by the dc.DrawText function over the rasterized svg image.

See discussion here: Adds basic text parsing by jamislike · Pull Request #94 · memononen/nanosvg

And see the image shot here, note that the text "abc" is drawn by the native dc.DrawText function.

FYI:

I have create a github repo to share my work on show SVG text by the nanosvg and doublemax's svg_panel.cpp/h.

See here: asmwarrior/SvgPanel: a wxPanel which can show svg image and simple text labels
