Define a button widget and provides the interfaces to be operational.
Notes
- The background image of button horizontally split into 5 parts and each part indicates one state. If the background of button is some area in the image, the area can be specified by using image_valid_area().
Background image of button horizontally split into 5 parts
For example. There is an image of size 520 * 70 pixels, and a button background image is just 470 * 23 pixels at position (0, 0). int main()
{
nana::form form;
nana::button btn(form, 5, 5, 94, 23);
btn.image(STR("button_image.bmp"));
btn.image_valid_area(nana::arrange::horizontal, nana::rectangle(0, 0, 94 * 5, 23));
form.show();
nana::exec();
}
The button splits the area of image into 5 parts for each state. The order of parts are same with the order of definition of elements of enum in type button::state.
- An image state can be disabled by calling image_enable() method. If a state is disabled, the button would averagely split the area of image into parts for each enabled state.
- Examples:
- a_group_impl.cpp, audio_player.cpp, background-effects.cpp, drag-button.cpp, example.button.cpp, example_menu.cpp, group.cpp, helloword_quit.cpp, helloworld_demo.cpp, listbox_inline_widget.cpp, loader_2.cpp, menu_popuper.cpp, MontiHall.cpp, place_login.cpp, widget_show2.cpp, and window-dragger.cpp.
