Member Function Documentation

void TextEdit::Activated (  bool bIsActive )  [virtual]

Description: This is a callback member that can be overloaded by derived classes to learn when the view is activated and when it is deactivated. The bIsActive parameter tell whether the focus was lost or gained. The view has focus when it is the active view in the active window. Note: This is a hook function that is called by the system to notify about an event. You should never call this member yourself. The window is locked when this member is called. Parameters: bIsActive   - true if the view gain and false if it loose focus. See also: MakeFocus(), WindowActivated() Author: Kurt Skauen ([email protected]) Reimplemented from os::View.

void TextEdit::AddUndoNode (  UndoNode * psNode )

void TextEdit::Clear (  )

void TextEdit::ClearSelection (  )

void TextEdit::CommitEvents (  )

void TextEdit::Delete (  )

void TextEdit::Delete (  IPoint cStart, IPoint cEnd, bool bMakeUndo = true )

void TextEdit::DrawCursor (  View * pcView = NULL, float vHOffset = 0.0f, float vVOffset = 0.0f )

void TextEdit::FontChanged (  Font * pcNewFont )  [virtual]

Description: FontChanged() is a virtual hook function that can be overloaded by inheriting classes to track changes to the view's font. This hook function is called whenver the font is replaced through the View::SetFont() member or if the currently assigned font is modified in a way that whould alter the graphical appearance of the font. Note: View::SetFont() will call FontChanged() syncronously and will cause FontChanged() to be called even if the view is not yet added to a window. Changes done to the font-object cause a message to be sendt to the window thread and FontChanged() will then be called asyncronously from the window thread when the message arrive. For this reason it is only possible to track changes done to the font object itself when the view is added to a window. Parameters: pcNewFont   Pointer to the affected font (same as returned by GetFont()). See also: SetFont(), os::Font Author: Kurt Skauen ([email protected]) Reimplemented from os::View.

void TextEdit::FrameSized (  const Point & cDelta )  [virtual]

Description: Overload this member if you need to know when the view is resized. Note: This member is called after the view is resized. If you need the old size you can subtract the cDelta calue from the current size. Parameters: cDelta   The distance the bottom/right corner was moved relative to the upper/left corner. See also: FrameMoved(), SetFrame, ResizeBy(), ResizeTo() Author: Kurt Skauen ([email protected]) Reimplemented from os::View.

void TextEdit::Paint (  const Rect & cUpdateRect )  [virtual]

Description: Note: Warning: Parameters: cUpdateRect   A rectangle enclosing all damaged areas. This is just a rough "worst-case", further fine-grained clipping will be performed by the Application Server to avoid updating non-damaged pixels and make the update as fast and flicker-free as possible.
