Detailed Description

The vpDisplayGTK allows to display image using the GTK 3rd party library. Thus to enable this class GTK should be installed. Installation instructions are provided here https://visp.inria.fr/3rd_gtk.

The example below shows how to display an image with this video device.

#include <visp3/core/vpImagePoint.h>
#include <visp3/gui/vpDisplayGTK.h>
#include <visp3/io/vpImageIo.h>
int main()
{
#if defined(VISP_HAVE_GTK)
vpImage<unsigned char> I; // Grey level image
// Read an image in PGM P5 format
#ifdef _WIN32
vpImageIo::read(I, "C:/temp/ViSP-images/Klimt/Klimt.pgm");
#else
vpImageIo::read(I, "/local/soft/ViSP/ViSP-images/Klimt/Klimt.pgm");
#endif
// Initialize the display with the image I. Display and image are
// now link together.
d.init(I);
// Specify the window location
// Set the display window title
vpDisplay::setTitle(I, "My GTK display");
// Set the display background with image I content
// Draw a red rectangle in the display overlay (foreground)
vpDisplay::displayRectangle(I, 10, 10, 100, 20, vpColor::red, true);
// Draw a red rectangle in the display overlay (foreground)
vpImagePoint topLeftCorner;
topLeftCorner.set_i(50);
topLeftCorner.set_j(10);
vpDisplay::displayRectangle(I, topLeftCorner, 100, 20, vpColor::green, true);
// Flush the foreground and background display
// Get non blocking keyboard events
std::cout << "Check keyboard events..." << std::endl;
char key[10];
bool ret;
for (int i=0; i< 200; i++) {
bool ret = vpDisplay::getKeyboardEvent(I, key, false);
if (ret)
std::cout << "keyboard event: key: " << "\"" << key << "\"" << std::endl;
}
// Get a blocking keyboard event
std::cout << "Wait for a keyboard event..." << std::endl;
ret = vpDisplay::getKeyboardEvent(I, key, true);
std::cout << "keyboard event: " << ret << std::endl;
if (ret)
std::cout << "key: " << "\"" << key << "\"" << std::endl;
// Wait for a click in the display window
std::cout << "Wait for a button click..." << std::endl;
#endif

Constructor & Destructor Documentation

◆ vpDisplayGTK() [1/6]

vpDisplayGTK::vpDisplayGTK ( )

Basic constructor.

To initialize the window position, title and size you may call init(vpImage<unsigned char> &, int, int, const std::string &) or init(vpImage<vpRGBa> &, int, int, const std::string &).

#include <visp3/core/vpImage.h>
#include <visp3/gui/vpDisplayGTK.h>
int main()
{
d.init(I, 100, 200, "My display");
}

)

Constructor that just initialize the display position in the screen and the display title.

Parameters
win_x,win_y: The window is set at position (win_x,win_y) with column index and row index respectively.

void vpDisplay::displayCharString ( const vpImage< vpRGBa > &  I,
int  i,
int  j,
const char *  string,

)
staticinherited

Display a string at the image point (i,j) location. Use rather displayText() that does the same.

To select the font used to display the string, use setFont().

Parameters
I: Image associated to the display.
i,j: Upper left image point location of the string in the display.
string: String to display in overlay.
color: String color.

Parameters
I: The image associated to the display.

◆ getKeyboardEvent() [3/8]

bool vpDisplay::getKeyboardEvent ( const vpImage< unsigned char > &  I,
char *  key,
bool  blocking = true 
)
staticinherited

Get a keyboard event.

Parameters
I[in] : The displayed image.
