C++ wxWidgets-cross-platform GUI library for C++

Example

wxButton* button = new wxButton(parent, wxID_ANY, "Click me");

Scenario

In a chat application, you can create a button for sending messages. This button can be instantiated using the wxButton class, specifying the parent window, a unique identifier, and the button label.

Example

Bind(wxEVT_BUTTON, &MyFrame::OnButtonClick, this, button->GetId());

Scenario

After creating a button, you can bind an event handler function to handle button clicks. This allows you to define custom behavior when the button is clicked, such as sending a message in a chat application.

Example

sizer->Add(button, wxSizerFlags().Expand());

Scenario

In a form-based application, you may want to arrange multiple GUI elements in a specific layout. wxWidgets provides layout managers, such as wxBoxSizer and wxGridSizer, to organize elements horizontally, vertically, or in a grid.

Example

wxFile file("example.txt", wxFile::write);

Scenario

For applications that need to read from or write to files, wxWidgets offers classes like wxFile for file I/O operations. This allows you to open, read, write, and close files seamlessly across different platforms.

Example

dc.DrawLine(10, 10, 100, 100);

Scenario

In a drawing application, you can use wxWidgets to draw lines, shapes, and text on a canvas. The wxDC class provides methods for drawing primitives and performing various graphic operations.
