@class wxWebViewChromium
|
|
|
|
wxWebViewChromium is a Chromium backend for wxWebView based on the
|
|
Chromium Embedded Framework (CEF3). The current CEF3 required version is
|
|
3.3239.1723. This backend is available for Windows, Linux and OS X only.
|
|
|
|
@section requirements CEF3 Requirements
|
|
|
|
If you are compiling your own copy of CEF3 then your compile flags must
|
|
match those you are using to compile wxWidgets. Specifically on Windows
|
|
it is likely you will need to adjust the following properties in the CEF3
|
|
provided build files:
|
|
|
|
- C/C++ - Code Generation - Runtime Library - Multithreaded [Debug] DLL
|
|
- C/C++ - Code Generation - Enable C++ Exceptions - Yes
|
|
- C/C++ - Language - Enable Run-Time Type Information - Yes
|
|
|
|
The following release branches of CEF have been tested: 3.3239.1723.
|
|
|
|
@section instructions Build Instructions
|
|
|
|
__General__
|
|
|
|
The wxWebViewChromium backend is built into a separate webview_chromium
|
|
library which depends on the webview library.
|
|
|
|
When building with CMake enable wxUSE_WEBVIEW_CHROMIUM and CEF will
|
|
automatically downloaded during configuration based on your platform.
|
|
|
|
For other build systems please follow the following instructions:
|
|
|
|
Once you have a copy of CEF3, either from compiling it yourself or using
|
|
prebuilt binaries you should copy it into `wx_root/3rdparty/cef`. To run the
|
|
webview_chromium sample you need to copy the CEF3 resources into the
|
|
sample directory. The following files need to be copied:
|
|
|
|
- The shared objects in the wx_root/3rdparty/cef/Debug or
|
|
wx_root/3rdparty/cef/Release folder, depending on your build type.
|
|
- The contents of the wx_root/3rdparty/cef/Resources folder.
|
|
|
|
When building wxWidgets you need to ensure wxWebViewChromium is enabled,
|
|
either by passing --enable-webviewchromium for autoconf based builds or
|
|
setting wxUSE_WEBVIEW_CHROMIUM equal to 1 in setup.h for Visual Studio
|
|
based builds.
|
|
|
|
|
|
__Mac OS X Platform__
|
|
|
|
OS X 10.9 or above is required.
|
|
|
|
Due to the application bundle structure on OS X, wxWebviewChromium is a
|
|
little complicated than on Windows/Linux platforms. An extra helper
|
|
application for executing separate Chromium processes(renderer, plugin,
|
|
etc) is required.
|
|
|
|
For applications using wxWebviewChromium below are details steps to make
|
|
is worked, based off the webview_chromium sample bakefile.
|
|
|
|
1. Build the webview_chromium library.
|
|
- Use system tool `install_name_tool -change` to correct `Chromium
|
|
Embedded Framework.framework/Chromium Embedded Framework` location.
|
|
2. Compiled/link/package the `helper` app:
|
|
- Require `process_helper_mac.cpp`
|
|
- Reuqire link frameworks: Chromium Embedded Framework.framework,
|
|
AppKit.frameworks.
|
|
- Reuqire app bundle configuration: Info.plist
|
|
- Use system tool `install_name_tool -change` to correct `Chromium
|
|
Embedded Framework.framework/Chromium Embedded Framework` location.
|
|
3. Compiled/link/package the `webviewchromium` app:
|
|
- Require `webview.cpp`
|
|
- Reuqire link frameworks: Chromium Embedded Framework.framework,
|
|
AppKit.frameworks.
|
|
- Require app bundle configuration: Info.plist
|
|
- Use system tool `install_name_tool -change` to correct `Chromium
|
|
Embedded Framework.framework/Chromium Embedded Framework` location.
|
|
4. Create a `Contents/Frameworks` directory in `webviewchromium.app` bundle
|
|
and copy `helper.app`, `webviewchromium.dylib`, 'webview.dylib'
|
|
and `Chromium Embedded Framework` into it.
|
|
5. Use `samples/webview_chromium/mac/tools/make_more_helper.sh` to make
|
|
sub-process helper app bundles based on `helper` app.
|
|
|
|
Below is the wxWebviewChromium sample app bundle directory structure:
|
|
|
|
webview_chromium.app
|

@section differences API Differences
|
|
|
|
wxWebViewChromium aims to support the full wxWebView API, but there are
|
|
some features which are currently unsupported by the CEF3 API, these are:
|
|
|
|
- GetSelectedSource/GetSelectedText: returns ""
|
|
- HasSelection: returns false
|
|
- IsEditable: returns false
|
|
- CanUndo/CanRedo/CanCut/CanCopy/CanPaste: returns true
|
|
- Find: returns -1
