Méthodes protégées

Méthode Description
CalculateFont ( OLVColumn column, bool isHot, bool isPressed ) : Font

What font should be used to draw the header text?
CalculateHeight ( Graphics g ) : int

Calculate how height the header needs to be
CalculateStyle ( OLVColumn column, bool isHot, bool isPressed ) : BrightIdeasSoftware.HeaderStateStyle

What style should be applied to the header?
CreateToolTip ( ) : void

Create a native tool tip control for this listview
CustomDrawHeaderCell ( Graphics g, int columnIndex, int itemState ) : void

Draw one cell of the header
DrawFilterIndicator ( Graphics g, Rectangle r ) : Rectangle

Draw an indication that this column has a filter applied to it
DrawHeaderImageAndText ( Graphics g, Rectangle r, OLVColumn column, BrightIdeasSoftware.HeaderStateStyle stateStyle ) : void

Draw the header's image and text
DrawThemedBackground ( Graphics g, Rectangle r, int columnIndex, bool isSelected ) : void

Draw a more-or-less pure themed header background.
DrawThemedSortIndicator ( Graphics g, Rectangle r ) : void

Draw a sort indicator using themes
DrawUnthemedBackground ( Graphics g, Rectangle r, int columnIndex, bool isSelected, BrightIdeasSoftware.HeaderStateStyle stateStyle ) : void

Draw a background for the header, without using Themes.
DrawUnthemedSortIndicator ( Graphics g, Rectangle r ) : Rectangle

Draw a sort indicator without using themes
HandleDestroy ( Message &m ) : bool

Handle when the underlying header control is destroyed
HandleLayout ( Message &m ) : bool

The message divides a ListView's space between the header and the rows of the listview. The WINDOWPOS structure controls the headers bounds, the RECT controls the listview bounds.
HandleMouseMove ( Message &m ) : bool

Handle the MouseMove windows message
HandleNotify ( Message &m ) : bool

Handle the Notify windows message
HandleSetCursor ( Message &m ) : bool

Handle the SetCursor windows message
HasFilterIndicator ( OLVColumn column ) : bool

Should the given column be drawn with a filter indicator against it?
HasNonThemedSortIndicator ( OLVColumn column ) : bool

Should the given column show a non-themed sort indicator?
HasSortIndicator ( OLVColumn column ) : bool

Should the given column show a sort indicator?
NeedsCustomDraw ( ) : bool

Does this header need to be custom drawn?

Word wrapping and colored text require custom drawning. Funnily enough, we can change the font natively.
