Detailed Description

Display for windows using Direct3D.

Direct3D is part of the DirectX API available under Windows operating systems.

Warning: Requires DirectX9 SDK to compile and DirectX9 DLLs to run.

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

#include <visp3/core/vpConfig.h>
#include <visp3/io/vpImageIo.h>
#include <visp3/gui/vpDisplayD3D.h>
int main()
{
#if defined(VISP_HAVE_D3D9)
  vpImage<unsigned char> I; // Grey level image
  // Read an image in PGM P5 format
  vpImageIo::read(I, "C:/temp/ViSP-images/Klimt/Klimt.pgm");
  vpDisplayD3D d;
  // Initialize the display with the image I. Display and image are
  // now link together.
  d.init(I);
  // Specify the window location
  vpDisplay::setWindowPosition(I, 400, 100);
  // Set the display window title
  vpDisplay::setTitle(I, "My Direct 3D display");
  // Set the display background with image I content
  vpDisplay::display(I);
  // Draw a red rectangle in the display overlay (foreground)
  vpImagePoint topLeftCorner;
  topLeftCorner.set_i(10);
  topLeftCorner.set_j(20);
  vpDisplay::displayRectangle(I, topLeftCorner, 100, 20, vpColor::red, true);
  // Flush the foreground and background display
  vpDisplay::flush(I);
  // Wait for a click in the display window
  vpDisplay::getClick(I);
#endif
}

bool vpDisplayWin32::getClick ( bool blocking = true )

protectedvirtualinherited

Wait for a click from one of the mouse button.

Parameters

blocking

[in] : Blocking behavior.

When set to true, this method waits until a mouse button is pressed and then returns always true.
When set to false, returns true only if a mouse button is pressed, otherwise returns false.

Returns

true if a button was clicked. This is always the case if blocking is set to true.
false if no button was clicked. This can occur if blocking is set to false.

When set to true, this method waits until a key is pressed and then returns always true.
When set to false, returns true only if a key is pressed, otherwise returns false.

Returns

true if a key was pressed. This is always the case if blocking is set to true.
false if no key was pressed. This can occur if blocking is set to false.
