\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.
See below the example used to generate the figure:
{@code
int main(int argc, char *argv[])
{
int value = 50;
int value2 = 0;
namedWindow("main1",WINDOW_NORMAL);
namedWindow("main2",WINDOW_AUTOSIZE | CV_GUI_NORMAL);
createTrackbar( "track1", "main1", &value, 255, NULL);
String nameb1 = "button1";
String nameb2 = "button2";
createButton(nameb1,callbackButton,&nameb1,QT_CHECKBOX,1);
createButton(nameb2,callbackButton,NULL,QT_CHECKBOX,0);

\defgroup highgui_winrt WinRT support
This figure explains new functionality implemented with WinRT GUI. The new GUI provides an Image control,
and a slider panel. Slider panel holds trackbars attached to it.
Sliders are attached below the image control. Every new slider is added below the previous one.
See below the example used to generate the figure:
{@code

/** \brief Creates a window.
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 cv::destroyWindow or cv::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:
- **WINDOW_NORMAL or WINDOW_AUTOSIZE:** WINDOW_NORMAL enables you to resize the
window, whereas WINDOW_AUTOSIZE adjusts automatically the window size to fit the
displayed image (see imshow ), and you cannot change the window size manually.
- **WINDOW_FREERATIO or WINDOW_KEEPRATIO:** WINDOW_FREERATIO adjusts the image
with no respect to its ratio, whereas WINDOW_KEEPRATIO keeps the image ratio.
- **WINDOW_GUI_NORMAL or WINDOW_GUI_EXPANDED:** WINDOW_GUI_NORMAL is the old way to draw the window
without statusbar and toolbar, whereas WINDOW_GUI_EXPANDED is a new enhanced GUI.
By default, flags == WINDOW_AUTOSIZE | WINDOW_KEEPRATIO | WINDOW_GUI_EXPANDED

/** \brief Displays an image in the specified window.
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 or 64-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, cv::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 cv::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)
