Creating a basic form

This is the most basic example of a uil app

int WinMain(HINSTANCE, HINSTANCE, LPSTR, int){
    uil::Form oForm;
    oForm.Run();
}

Creating a more advanced form

Step 1 - Create a form subclass

struct MyForm : uil::Form{
    MyForm(){}
};

Step 2 - Add control members

struct MyForm : uil::Form{
    MyForm(){}
    uil::Button oButton;
};

Step 3 - Initialize members

Controls require a parent so the form is passed into the constructor.

struct MyForm : uil::Form{
    MyForm() : oButton(this){}
    uil::Button oButton;
};

Step 4 - Set properties

struct MyForm : uil::Form{
    MyForm() : oButton(this){
        oButton.Text(_T("Click Me"));
        oButton.Move(50, 50, 100, 20);
    }
    uil::Button oButton;
};

Step 5 - Attach event handlers

Here a Lambda is connected to the button's click event that changes the button's text.

struct MyForm : uil::Form{
    MyForm() : oButton(this){
        oButton.Text(_T("Click Me"));
        oButton.Move(50, 50, 100, 20);
        oButton.ClickEvent.Connect( [ this ] ( ) { 
            oButton.Text(_T("Clicked!")); 
        });
    }
    uil::Button oButton;
};

The app's WinMain has changed only slightly

int __stdcall WinMain(HINSTANCE, HINSTANCE, LPSTR, int){
    MyForm oForm;
    oForm.Run();
    return 0;
}
