@defgroup highgui High-level GUI
While OpenCV was designed for use in full-scale applications and can be used within functionally
rich UI frameworks (such as Qt\*, WinForms\*, or Cocoa\*) or without any UI at all, sometimes there
it is required to try functionality quickly and visualize the results. This is what the HighGUI
module has been designed for.
It provides easy interface to:
- Create and manipulate windows that can display images and "remember" their content (no need to
handle repaint events from OS).
- Add trackbars to the windows, handle simple mouse events as well as keyboard commands.
@{
@defgroup highgui_opengl OpenGL support
@defgroup highgui_qt Qt New Functions
This figure explains new functionality implemented with Qt\* GUI. The new GUI provides a statusbar,
a toolbar, and a control panel. The control panel can have trackbars and buttonbars attached to it.
If you cannot see the control panel, press Ctrl+P or right-click any Qt window and select **Display
properties window**.
- To attach a trackbar, the window name parameter must be NULL.
- To attach a buttonbar, a button must be created. If the last bar attached to the control panel
is a buttonbar, the new button is added to the right of the last button. If the last bar
attached to the control panel is a trackbar, or the control panel is empty, a new buttonbar is
created. Then, a new button is attached to it.

/** @brief Creates a window.
@param winname Name of the window in the window caption that may be used as a window identifier.
@param flags Flags of the window. The supported flags are:
> - **WINDOW_NORMAL** If this is set, the user can resize the window (no constraint).
> - **WINDOW_AUTOSIZE** If this is set, the window size is automatically adjusted to fit the
> displayed image (see imshow ), and you cannot change the window size manually.
> - **WINDOW_OPENGL** If this is set, the window will be created with OpenGL support.
The function namedWindow creates a window that can be used as a placeholder for images and
trackbars. Created windows are referred to by their names.
If a window with the same name already exists, the function does nothing.
You can call destroyWindow or destroyAllWindows to close the window and de-allocate any associated
memory usage. For a simple program, you do not really have to call these functions because all the
resources and windows of the application are closed automatically by the operating system upon exit.
@note
Qt backend supports additional flags:
- **CV_WINDOW_NORMAL or CV_WINDOW_AUTOSIZE:** CV_WINDOW_NORMAL enables you to resize the
window, whereas CV_WINDOW_AUTOSIZE adjusts automatically the window size to fit the
displayed image (see imshow ), and you cannot change the window size manually.
- **CV_WINDOW_FREERATIO or CV_WINDOW_KEEPRATIO:** CV_WINDOW_FREERATIO adjusts the image
with no respect to its ratio, whereas CV_WINDOW_KEEPRATIO keeps the image ratio.
- **CV_GUI_NORMAL or CV_GUI_EXPANDED:** CV_GUI_NORMAL is the old way to draw the window
without statusbar and toolbar, whereas CV_GUI_EXPANDED is a new enhanced GUI.
By default, flags == CV_WINDOW_AUTOSIZE | CV_WINDOW_KEEPRATIO | CV_GUI_EXPANDED

running on your computer at that time. It returns the code of the pressed key or -1 if no key was
pressed before the specified time had elapsed.
@note
This function is the only method in HighGUI that can fetch and handle events, so it needs to be
called periodically for normal event processing unless HighGUI is used within an environment that

@param mat Image to be shown.
The function imshow displays an image in the specified window. If the window was created with the
CV_WINDOW_AUTOSIZE flag, the image is shown with its original size, however it is still limited by the screen resolution.
Otherwise, the image is scaled to fit the window. The function may scale the image, depending on its depth:
- If the image is 8-bit unsigned, it is displayed as is.
- If the image is 16-bit unsigned or 32-bit integer, the pixels are divided by 256. That is, the
value range [0,255\*256] is mapped to [0,255].
- If the image is 32-bit floating-point, the pixel values are multiplied by 255. That is, the
value range [0,1] is mapped to [0,255].
If window was created with OpenGL support, imshow also support ogl::Buffer , ogl::Texture2D and
cuda::GpuMat as input.
If the window was not created before this function, it is assumed creating a window with CV_WINDOW_AUTOSIZE.
If you need to show an image that is bigger than the screen resolution, you will need to call namedWindow("", WINDOW_NORMAL) before the imshow.
@note This function should be followed by waitKey function which displays the image for specified
milliseconds. Otherwise, it won't display the image. For example, waitKey(0) will display the window
infinitely until any keypress (it is suitable for image display). waitKey(25) will display a frame
for 25 ms, after which display will be automatically closed. (If you put it in a loop to read
videos, it will display the video frame-by-frame)

/** @brief Attaches a button to the control panel.
@param bar_name
Name of the button.
@param on_change Pointer to the function to be called every time the button changes its state.
This function should be prototyped as void Foo(int state,\*void); . *state* is the current state
of the button. It could be -1 for a push button, 0 or 1 for a check/radio box button.
@param userdata Pointer passed to the callback function.
@param type Optional type of the button.
- **CV_PUSH_BUTTON** Push button
- **CV_CHECKBOX** Checkbox button
- **CV_RADIOBOX** Radiobox button. The radiobox on the same buttonbar (same line) are
exclusive, that is only one can be selected at a time.
@param initial_button_state Default state of the button. Use for checkbox and radiobox. Its
value could be 0 or 1. *(Optional)*
The function createButton attaches a button to the control panel. Each button is added to a
buttonbar to the right of the last button. A new buttonbar is created if nothing was attached to the
control panel before, or if the last element attached to the control panel was a trackbar.
See below various examples of the createButton function call: :
@code
createButton(NULL,callbackButton);//create a push button "button 0", that will call callbackButton.
createButton("button2",callbackButton,NULL,CV_CHECKBOX,0);
createButton("button3",callbackButton,&value);
createButton("button5",callbackButton1,NULL,CV_RADIOBOX);
createButton("button6",callbackButton2,NULL,CV_PUSH_BUTTON,1);
