void TabView::AllAttached ( void ) [virtual]

Description:
TabView overloades AllAttached to set the window as it's message target.

Author:
Kurt Skauen (kurt@atheos.cx)

Reimplemented from os::View.

int TabView::AppendTab ( const char * pzTitle,

View * pcView = NULL

)

Description:
Add a new tab to the TabView. The new tab will be appended to the list and will appear rightmost. Each tab is associated with title that is printed inside it, and a View that will be made visible when the tab is selected or hidden when the tab is inactive. If you want to use the TabView to something else than flipping between views, you can pass a NULL pointer, or you can pass the same ViewPointer for all tabs. Then you can associate a message with the TabView that will be sendt to it's target everytime the selection change.
Note:
Views associated with tabs should *NOT* be attached to any other view when or after the tab is created. It will automatically be a child of the TabView when added to a tab.

Views associated with tabs *MUST* have the CF_FOLLOW_ALL flag set to be properly resized when the TabView is resized.
When a view is associated with a tab, the view will be resized to fit the interiour of the TabView.
Parameters:

pcTitle - The string that should appear inside the tab.

pcView - The View to be accosiated with the tab, or NULL.

Returns:
The zero based index of the new tab.

View * TabView::DeleteTab ( uint nIndex )

Description:
The tab at position nIndex is deleted, and the associated view is removed from the child list unless it is still associated with any of the remaining tabs. The view associated with the deleted tab is returned, and must be deleted by the caller if it is no longer needed.
Parameters:

nIndex - The zero based index of the tab to delete.

Returns:
Pointer to the view associated with the deleted tab.

void TabView::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.

Point TabView::GetPreferredSize ( bool bLargest ) const [virtual]

Description:
TabView overloads GetPreferredSize() and return the largest size returned by any of the views associated with the different tabs.
Returns:
The largest preffered size returned by it's childs.

Reimplemented from os::View.

uint TabView::GetSelection ( )

Description:
Returns the zero based index of the selected tab.
Note:
This index is also added to the notification sendt when the selection change. The selection is then added under the name "selection".
Returns:
The zero based index of the selected tab.

int TabView::GetTabCount ( ) const

Returns:
Tab count

const std::string & TabView::GetTabTitle ( uint nIndex ) const

Parameters:

nIndex - The zero based index of the tab.

Returns:
const reference to a STL string containing the title.

View * TabView::GetTabView ( uint nIndex ) const

Parameters:

nIndex - The zero based index of the tab.

Returns:
Pointer to the View associated with the tab.

int TabView::InsertTab ( uint nIndex,

const char * pzTitle,

View * pcView = NULL

)

Description:
Same as AppendTab() except that InsertTab() accept a zero based index at which the tab will be inserted. Look at AppendTab() to get the full thruth.
Note:
If the rightmost tab is selected, the selection will be moved to the previous tab, and a notification message (if any) is sendt.
Warning:
The index *MUST* be between 0 and the current number of tabs!
Parameters:

nIndex - The zero based position where the tab is inserted.

pcTitle - The string that should appear inside the tab.

pcView - The View to be accosiated with the tab, or NULL.

Returns:
The zero based index of the new tab (Same as nIndex).

void TabView::KeyDown ( const char * pzString,

const char * pzRawString,

uint32 nQualifiers

) [virtual]

Description:
Overload this member if your view need to handle keyboard input. This member is called to allow the view to handle M_KEY_DOWN messages. The most common members are exctracted from the message and passed as parameters but you might need to obtain the raw message with os::Looper::GetCurrentMessage() and find some members yourself if you the data you needed are not passed in.
For example if you need the raw key-code for the pressed key you will have to lookup the "_raw_key" member from the message.
Parameters:

pzString String containing a single UTF-8 encoded character. This is the character generated by the pressed key according to the current keymap accounting for any qualifiers that might be pressed.

pzRawString Same as pzString except that the key is converted without accounting for qualifiers. Ie. if 'A' is pressed while pressing <SHIFT> pzString will contain 'A' and pzRawString will contain 'a'.

nQualifiers Bitmask describing which qualifiers that was active when the key was pressed.

Reimplemented from os::View.

void TabView::MouseDown ( const Point & cPosition,

uint32 nButtons

) [virtual]

Description:
This member is called from the window thread whenever a mouse button is clicked above the view. You can overload this member if your view need to know about mouse-down events.
A view will not automatically take focus when clicked so if you want that behaviour you must call MakeFocus() from an overloaded version of this member.
The default implementation of this member will call MouseDown() on it's parent view if one exists.
Parameters:

cPosition Mouse position in the views coordinate system at the time the mouse was pressed.

nButtons Index of the pressed button. Buttons start at 1 for the left button, 2 for the right button, 3 for the middle button. Additional buttons might be supported by the mouse driver and will then be assigned numbers from 4 and up.

Reimplemented from os::View.

void TabView::MouseMove ( const Point & cNewPos,

int nCode,

uint32 nButtons,

Message * pcData

) [virtual]

Description:
This member is called from the window thread whenever the mouse is moved above the view or if the view have focus.
Oveload this member if your view need to handle mouse-move events.
The default implementation of this member will call MouseMove() on it's parent view if one exists.
Parameters:

cNewPos New mouse position given in the views coordinate system.

nCode Enter/exit code. This is MOUSE_ENTERED when the mouse first enter the view, MOUSE_EXITED when the mouse leaves the view, MOUSE_INSIDE whenever the mouse move withing the boundary of the view and MOUSE_OUTSIDE when the mouse move outside the view (will only happen if the view have focus).

nButtons Bitmask telling which buttons that are currently pressed. Bit 0 is button 1 (left), bit 1 is button 2 (right), and bit 2 is button 3 (middle), and so on.

pcData Pointer to a Message object containing the dragged data if the user is in the middle of a drag and drop operation. Otherwise this pointer is NULL. Look at BeginDrag() for a more detailed description of the drag and drop system.

Reimplemented from os::View.

void TabView::MouseUp ( const Point & cPosition,

uint32 nButtons,

Message * pcData

) [virtual]

Description:
This member is called from the window thread whenever a mouse button is released above the view. You can overload this member if your view need to know about mouse-up events or if your view support drag and drop.
If mouse-up was the result of ending a drag and drop operation the pcData member will point to a Message containing the dragged data. Look at BeginDrag() for a more detailed description of the drag and drop system.
The default implementation of this member will call MouseDown() on it's parent view if one exists.
Parameters:

cPosition Mouse position in the views coordinate system at the time the mouse was pressed.

nButtons Index of the pressed button. Buttons start at 1 for the left button, 2 for the right button, 3 for the middle button. Additional buttons might be supported by the mouse driver and will then be assigned numbers from 4 and up.

pcData Pointer to a Message object containing the dragged data if this mouse-up was the end of a drag and drop operation. If no data was dragged it will be NULL.

void TabView::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.

void TabView::SetSelection ( uint nIndex,

bool bNotify = true

Description:
Selects the given tab. If bNotify is true, and a messages has been assigned through Invoker::SetMessage() the message will be sendt to the target.
Parameters:

nIndex - The zero based index of the tab to select.
