Detailed Description

A class that can be used to display images in a window.

Every instance of this class will create and display its own independent window. Internally it uses an instance of mvIMPACT::acquire::display::ImageDisplay to display image data. The internal display object can be accessed by calling mvIMPACT::acquire::display::ImageDisplayWindow::GetImageDisplay().

Constructor & Destructor Documentation

ImageDisplayWindow()

ImageDisplayWindow ( const std::string & title )

inlineexplicit

Creates a new window that can be used to display image data and displays it.

This is an example of how to use the GetImageDisplay class. More details about this example.

Parameters

[in]

title

The title of the window (will be displayed in the windows title bar).

~ImageDisplayWindow()

~ImageDisplayWindow ( )

inline

destroys the display window and frees resources.

Member Function Documentation

GetImageDisplay()

ImageDisplay & GetImageDisplay ( void )

inline

Returns a reference to the actual display object associated with this window.

Examples

GenericInterfaceLayout.legacy.cpp, Properties.legacy.cpp, and SingleCapture.cpp.

GetMessageHandler()

TPreProcessMessage GetMessageHandler ( void ) const

inline

Returns the current message handler for this window.

See also

mvIMPACT::acquire::display::ImageDisplayWindow::SetMessageHandler()

Returns

The current message handler for this window.

SetMessageHandler()

void SetMessageHandler ( TPreProcessMessage handler )

inline

Installs a callback to handle the window messages.

See also

mvIMPACT::acquire::display::ImageDisplayWindow::GetMessageHandler()

Parameters

[in]

handler

Pointer to a function which is called by the windows procedure before the display update is done. If zero is passed here even the internal default handler will be disabled and WM_SIZE and WM_LBUTTONDBLCLK will no longer be handled internally.

SetRefreshTime()

void SetRefreshTime ( int time_ms )

inline

Defines the refresh time in ms.

This function can be used to define a refresh period that - when elapsed - will automatically repaint the window.

Parameters

[in]

time_ms

The refresh period for the window in ms. Passing 0 will disable the automatic repaint behaviour.
