Constructor & Destructor Documentation

TxqImageFrame::TxqImageFrame ( QString fileName, TxqMasterIoFrame * parent, const char * nm = 0, WFlags f = WType_TopLevel )

The constructor requires the image file and can also add the QWidget parent. Parameters: fileName   the image file name to either read or use as a key. parent   the parent widget which must be supplied. nm   the name of the widget which defaults to null. f   the window flags which default to WType_TopLevel.

TxqImageFrame::~TxqImageFrame ( ) [virtual]

The destructor.

TxqImageFrame::TxqImageFrame ( ) [private]

The default constructor is private in order to not be used.

Member Function Documentation

void TxqImageFrame::addMenuBarItems ( ) [protected, virtual]

Add the default menu bar items. Reimplemented from TxqFrame.

void TxqImageFrame::addSubMenuBarItems ( ) [protected, virtual]

Add the sub menu bar items The sub menubar items are any menus in the menubar that may need items inserted into it. Reimplemented from TxqFrame.

void TxqImageFrame::addWidgets ( ) [protected, virtual]

Add the widgets. Reimplemented from TxqFrame.

void TxqImageFrame::advance ( const QString fileName, int frameNumber )

Advance the movie. Parameters: filename   the fileName to either read or obtain the pixmap from the memory map. frameNumber   the frameNumber for this image.

void TxqImageFrame::clearMapElements ( unsigned int n )

clear N elements from the pixmap. Parameters: n   the number of elements to clear from memory. This method is used when the system memory is getting full.

void TxqImageFrame::clearMemory ( ) [signal]

signal emitted when needing to clear the pixmap map memory.

void TxqImageFrame::clearPixMaps ( )

Clear the pixmaps pointers from the pixmap map.

bool TxqImageFrame::close ( bool forceKill = FALSE ) [protected, virtual, slot]

Close and quit the window. Parameters: forceKill   the forceKill bool is set to false as a default. Reimplemented from TxqFrame.

void TxqImageFrame::closeSignal ( int indx ) [signal]

signal emitted when the window is closing. Parameters: indx   the index number of this frame.

bool TxqImageFrame::getPixmapMemory ( ) [inline]

Get the pixmap memory flag. Returns: the bool for determining if reading from memory the pixmaps. Definition at line 102 of file TxqImageFrame.h.

void TxqImageFrame::paintEvent ( QPaintEvent * ) [protected]

The paint event will paint the image onto the widget. Parameters: e   the QPaintEvent

void TxqImageFrame::print ( ) [virtual, slot]

slot to print the canvas. Reimplemented from TxqFrame.

void TxqImageFrame::readImage ( const QString fileName ) [protected]

read the image file and convert to a pixmap. Parameters: fileName   the filename to read and convert to a pixmap.

void TxqImageFrame::setFileName ( const QString fileName )

Set the filename. Parameters: fileName   the filename to read the image data. If using memory, then this filename is a key in the map.

void TxqImageFrame::setIndex ( int indx ) [virtual]

Set the window index. Parameters: indx   the window index number. Reimplemented from TxqFrame.

void TxqImageFrame::setPixmap ( QPixmap * pm )

Set the pixmap to write the image onto. Parameters: pm   the QPixmap pointer.

void TxqImageFrame::setPixmapMemory ( bool memory )

Set the memory flag. Parameters: memory   the memory flag if true, the pixmaps will be painted from memory
