C# Class SIL.FieldWorks.Common.Controls.DhListView

Derived from ListView, this class supports notifying the browse view when resizing the columns. This class holds the headers that show above columns of data that BrowseViewer knows about.

Inheritance: System.Windows.Forms.ListView, IFWDisposable

Méthodes publiques

Méthode	Description
CheckDisposed ( ) : void	Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.
DhListView ( BrowseViewer bv ) : System	Create one and set the browse view it belongs to.
ShowHeaderIcon ( int columnIndex, SortOrder sortOrder, ArrowSize size ) : void	Set the header icon. (Thanks to a post by Eddie Velasquez.)

Méthodes protégées

Méthode	Description
Dispose ( bool disposing ) : void	Releases the unmanaged resources used by the T:System.Windows.Forms.ListView and optionally releases the managed resources.
OnColumnRightClick ( int iItem, Point ptLoc ) : void	Handle a right click event in a column header.
OnHandleCreated ( EventArgs e ) : void
OnParentVisibleChanged ( EventArgs e ) : void
WndProc ( Message &m ) : void	Override of WndProc to handle the context menu or column resize on column headers. Necessary because ListView eats almost all mouse events, and does not provide any that can be used to handling right clicks in the header. Also couldn't use class wizard to handle WM_NOTIFY because it won't add HDN_ITEMCLICKA and HDN_DIVIDERDBLCLICKW

Private Methods

Méthode	Description
DhListView_DrawColumnHeader ( object sender, DrawListViewColumnHeaderEventArgs e ) : void
GetArrowBitmap ( ArrowType type, ArrowSize size ) : Bitmap	Create up/down icon (Adapted from a post by Eddie Velasquez.)
GetColumnIndexFromMousePosition ( Point pt ) : int
HandleColumnClick ( object sender, System.Windows.Forms.ColumnClickEventArgs e ) : void
HandleColumnReordered ( object sender, System.Windows.Forms.ColumnReorderedEventArgs e ) : void
IsThisColumnChangeAllowable ( int columnIndex, int currentWidth, int newWidth ) : bool	Determine if a column width change is acceptable.
ListView_ColumnWidthChanged ( Object sender, System.Windows.Forms.ColumnWidthChangedEventArgs e ) : void
ListView_ColumnWidthChanging ( Object sender, System.Windows.Forms.ColumnWidthChangingEventArgs e ) : void	Reject inappropriate column width changes. Helps to fix FWNX-1018. No column should be so small that compensating for ascending/descending icon size (m_imgList.ImageSize.Width) in DhListView_DrawColumnHeader would result in a negative width.
m_timer_Tick ( object sender, EventArgs e ) : void

public DhListView ( BrowseViewer bv ) : System
bv	BrowseViewer
Résultat	System

Dispose() protected méthode

Releases the unmanaged resources used by the T:System.Windows.Forms.ListView and optionally releases the managed resources.

protected Dispose ( bool disposing ) : void
disposing	bool	true to release both managed and unmanaged resources; false to release only unmanaged resources.
Résultat	void

OnColumnRightClick() protected méthode

Handle a right click event in a column header.

protected OnColumnRightClick ( int iItem, Point ptLoc ) : void
iItem	int	The i item.
ptLoc	Point	The pt loc.
Résultat	void

OnHandleCreated() protected méthode

protected OnHandleCreated ( EventArgs e ) : void
e	System.EventArgs	An that contains the event data.
Résultat	void

OnParentVisibleChanged() protected méthode

protected OnParentVisibleChanged ( EventArgs e ) : void
e	System.EventArgs
Résultat	void

ShowHeaderIcon() public méthode

Set the header icon. (Thanks to a post by Eddie Velasquez.)

public ShowHeaderIcon ( int columnIndex, SortOrder sortOrder, ArrowSize size ) : void
columnIndex	int	Index of the column.
sortOrder	SortOrder	The sort order.
size	ArrowSize	The size.
Résultat	void

WndProc() protected méthode

Override of WndProc to handle the context menu or column resize on column headers. Necessary because ListView eats almost all mouse events, and does not provide any that can be used to handling right clicks in the header. Also couldn't use class wizard to handle WM_NOTIFY because it won't add HDN_ITEMCLICKA and HDN_DIVIDERDBLCLICKW

protected WndProc ( Message &m ) : void
m	System.Windows.Forms.Message	The Windows Message to process
Résultat	void
