examples_wxwidgets's Issues

Broken links in readme file

There are some broken links in readme file like "Application".

Low Resolution examples under macOS

I only tested OpenGL example, but by default it provides very low resolution on Retina display.

Something like this needs to be added to CMake to fix it:

add_custom_target(NSPrincipalClass ALL plutil -replace NSPrincipalClass -string NSApplication ${CMAKE_BINARY_DIR}/${PROJECT_NAME}.app/Contents/Info.plist DEPENDS ${PROJECT_NAME})
add_custom_target(NSHighResolutionCapable ALL plutil -replace NSHighResolutionCapable -bool true ${CMAKE_BINARY_DIR}/${PROJECT_NAME}.app/Contents/Info.plist DEPENDS ${PROJECT_NAME})

CMake Error

CMake Deprecation Warning at src/Controls/StaticText/CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

WX version: wxwidgets-gtk3-3.2.2.1-2
CMake version: cmake-3.27.1-1

i can fix it by changing cmake version but for others i left it here

Some tips to help compile in Windows

Hi, my system is:

Windows 7 x64
wxWidgets 3.1.4 (build=release shared=0 monolithic=0)
GCC MinGW 10.2.0
Visual Studio 2017
cmake 3.18.1

I just wanted to know if my wxWidgets compile is good so I downloaded this project and compiled with VS 2017 and GCC

With VS2017

Configuring with cmake it was a PITA, because you have to either create environmente variables or just pass the variables to cmake to configure wxWidgets, here are the variables, the importants are: wxWidgets_ROOT_DIR, wxWidgets_LIB_DIR, wxWidgets_CONFIGURATION, but after creating those variables cmake was complaining about the variable: wxWidgets_LIBRARIES, and the docs says that this variable will be setted by cmake, don't know why was complaining sure I did something wrong but I don't know, at the end just either create environment variables or just pass the variables to cmake, I created all env vars and just:

cmake -G "Visual Studio 15 2017 Win64" ..

Not tested all projects but the ApplicationAndMain ApplicationAndMain2 gives undefined reference to main, this happens because VS uses its own main function for GUIs that is WinMain, the only way to solve this is to change subsystem to console but this shows the console window, even using the FreeConsole() function to hide the window it still appears for less than 2 seconds

With MinGW GCC

I also have GCC 7.1 and it is my default compiler but this version does not fully support C++17 so I had to configure cmake to select the GCC 10.2 like this:

set mingw64_path=c:/mingw-w64/x86_64-10.2.0-posix-seh/mingw64/bin

set CC=%mingw64_path%/gcc.exe
set CPP=%mingw64_path%/g++.exe
set MAKE=%mingw64_path%/mingw32-make.exe
set RC=%mingw64_path%/windres.exe

cmake -DCMAKE_MAKE_PROGRAM=%MAKE% -DCMAKE_C_COMPILER=%CC% -DCMAKE_CXX_COMPILER=%CPP% -DCMAKE_RC_COMPILER=%RC% -DCMAKE_VERBOSE_MAKEFILE=ON -G "MinGW Makefiles" ..

This generated the Makefiles with no problems

Also there was undefined reference to many functions with the RichTextCtrl project , after digging in internet I found that the libs should be in a specific order and since there are many libs I found this and I changed the file link.txt this part:

... --minor-image-version,0, @CMakeFiles\RichTextCtrl.dir\linklibs.rsp

to

... --minor-image-version,0,--start-group @CMakeFiles\RichTextCtrl.dir\linklibs.rsp

and that solved the libs and the project compiled fine

cmake

Now some tips to get better experience with both MSVC compiler and GCC

• Check if wxWidgets_ROOT_DIR, wxWidgets_LIB_DIR:PATH, wxWidgets_CONFIGURATION vars are set if not show a message that these vars must be set
• Check for minimun compiler version to run C++17 I think GCC is 7 or 8, dont know about MSVC
• Detect wxWidgets compilation options like static (passing -DwxWidgets_USE_STATIC:BOOL=ON) in GCC add -static option and MSVC add option /MT for release and /MTd for debug (passing -DwxWidgets_USE_DEBUG:BOOL=ON) here more info
• Add to the linker the --start-group to solves the libs order

wxEVT_LEFT_UP mouseEvent not triggering in the webview sample

Hi!

I've added in the WebFrame::WebFrame constructor in the webview sample:

https://github.com/wxWidgets/wxWidgets/blob/WX_3_0_BRANCH/samples/webview/webview.cpp

the following event binding:

panel->Bind(wxEVT_LEFT_UP, [&](wxMouseEvent& event) {
    wxMessageBox(wxString::Format("The frame is clicked at {x=%d, y=%d}", event.GetPosition().x, event.GetPosition().y), "FrameClick", wxID_ANY) ;
    std::cout << event.GetPosition().x << " , " << event.GetPosition().y << std::endl;
    mouse_position = event.GetPosition();
});

But I do not get any output

What am I doing wrong? How to make it work?

PS: I know my question is not stictly related to this github's repo, but, may be, you can give me some helpful hints

BookControls/Notebook assertion failed in InsertPage(): "invalid notebook imagelist"

Got this assertion failure when tried to run BookControls/Notebook:

ApplicationIcon example does not properly load icon on linux

"Failed to load image from file "Resources/Gammasoft.png"

This happens if I run the ApplicationIcon example from anywhere except:

~/Examples_wxWidgets/src/Applications/ApplicationIcon

In which case I invoke execution with this relative path:

../../../build/src/Applications/ApplicationIcon/ApplicationIcon

because at least there the png is under the Resources directory.

HelloWorldPaint not showing the expected text

HelloWorldPaint not showing the expected text draw as it is hidden by the panel, commenting out the panel will make the text "the drawing " shows directly on the wxFrame (I tested it using Visual Studio 2019).

private:
//wxPanel* panel = new wxPanel(this);
