Member Function Documentation

TStreamable * TColorDisplay::build ( ) [static]

Creates a new TColorDisplay. Used to recover the view from a stream. Called to create an object in certain stream-reading situations. Reimplemented from TView.

void TColorDisplay::draw ( ) [virtual]

Draws the view with given text and current color. Reimplemented from TView.

void TColorDisplay::handleEvent ( TEvent & event ) [virtual]

Calls TView::handleEvent() and redraws the view as appropriate in response to the cmColorBackgroundChanged and cmColorForegroundChanged broadcast events. Reimplemented from TView.

void * TColorDisplay::read ( ipstream & is ) [protected, virtual]

Used to recover the view from a stream. Reads from the input stream `is'. Reimplemented from TView.

void TColorDisplay::setColor ( uchar * aColor ) [virtual]

Change the currently displayed color. Sets color to `aColor', broadcasts the change to the owning group, then calls drawView().

void TColorDisplay::write ( opstream & os ) [protected, virtual]

Used to store the view in a stream. Writes to the output stream `os'. Reimplemented from TView.
