Detailed Description

A draw window independant from main application.

The class creates a window and the message handler and connects them on intstance level. That is you don't have to worry about how to propagate 'slef' to the message handler ProcessMessage().

Actual drawing happens in a background buffer which should be copied to the screen by calling WndUpdate(). The standard message handler implementation does so for several system messages like window movement.

When drawing takes to much time it is a good idea to do that in a separate thread.

Constructor & Destructor Documentation

mbo::MboDrawWin::MboDrawWin	(	int	nSizeX = 400,
		int	nSizeY = 300,
		const MboString &	strWndClassName = "MboDrawWin",
		bool	bStart = true
	)			[explicit]

Creates a window and all necessary resources (classes, handlers).

Parameters:

	nSizeX	outer width of window
	nSizeY	outer height of window
	strWndClassName	the name of the window class that will be returned by WndClassName() if not overwritten.
	bStart	whether to create window and start handler directly. If you plan to override window creation functions in a derived class this parameter must be set false.

Note:

When using this constructor the created window is not resizeable.

Warning:

There is a known problem with small windows. When the window widsth is smaller than the width needed to display any configured frame or system menu elements the client area gets the size as configured and a transparent area is used to fillup the real window area. The problem however is inherent to the WINAPI.

mbo::MboDrawWin::MboDrawWin	(	int	nSizeX,
		int	nSizeY,
		int	nMinSizeX,
		int	nMinSizeY,
		int	nMaxSizeX,
		int	nMaxSizeY,
		const MboString &	strWndClassName = "MboDrawWin",
		bool	bStart = true
	)

Creates a window and all necessary resources (classes, handlers).

Parameters:

	nSizeX	outer width of window
	nSizeY	outer height of window
	nMinSizeX	minimum allowed outer width of window
	nMinSizeY	minimum allowed outer height of window
	nMaxSizeX	maximum allowed outer width of window
	nMaxSizeY	maximum allowed outer height of window
	strWndClassName	the name of the window class that will be returned by WndClassName() if not overwritten.
	bStart	whether to create window and start handler directly. If you plan to override window creation functions in a derived class this parameter must be set false.

Note:

When using this constructor the created window is resizeable as long as MinSizeX / MaxSizeX or MinSizeY / MaxSizeY differ.

All Size values area automatically corrected. That is you have exchanged minimum and maximum values the constructor will change them back and if the Size value is smaller than the MinSize value the MinSizeValue will be used and finally if the Size value is greater than the MxSize value then the MaxSize value will be used.

Warning:

There is a known problem with small windows. When the window widsth is smaller than the width needed to display any configured frame or system menu elements the client area gets the size as configured and a transparent area is used to fillup the real window area. The problem however is inherent to the WINAPI.

virtual void mbo::MboDrawWin::WndShow

(

bool

bActive = true

)

[virtual]

Show the window and optionally activate it.

Parameters:

bActive

whether to activate the window.

Note:

This does not restore the window. That is a minimized window remains minimized after this call.

See also:

WndRestore

virtual void mbo::MboDrawWin::WndHide

(

)

[virtual]

Hide the window .

virtual void mbo::MboDrawWin::WndRestore

(

)

[virtual]

Restore the window, does neither show nor activate it.

See also:

WndShow

virtual void mbo::MboDrawWin::WndSetSize	(	int	nSizeX,
		int	nSizeY
	)			[virtual]

Resize the window by specifying its outer size.

You can only change the size of the window within minimum and maximum values specified. To Check these you can use the following methods:

• GetMinSizeX()
• GetMinSizeY()
• GetMaxSizeX()
• GetMaxSizeY() Lower values are replaced by their minimum values and higher values are replaced by their maximum values.

Parameters:

	nSizeX	new width of window
	nSizeY	new height of window

virtual void mbo::MboDrawWin::WndSetPosition	(	int	nPosX,
		int	nPosY
	)			[virtual]

Move the window to the specifying coordinates.

Note:

This is ignored if not running (in _DEBUG mode it uses an assertion).

Parameters:

	nPosX	new X coordinate of window (top/right edge)
	nPosY	new Y coordinate of window (top/right edge)

virtual void mbo::MboDrawWin::WndDraw

(

)

[virtual]

The actual drawing routine which is only called upon window creation once. It calles WndUpdate() to show the new contents.

Derived classes should therfore override this method and do its actual drawing there and call WndUpdate() when finished. The other way to draw the window is to inherit this function as is and perform drawing in specialized methods that are controlled from outside this class. In that case those methods need to ensure WndUpdate() gets called to make the new contents visible.

virtual void mbo::MboDrawWin::OnWndSized

(

)

[virtual]

Called when the window has been resized. The default implementation simply calls WndDraw(). A derived class however might want to change internal information to be able to modify what can be shown with new window size.

virtual bool mbo::MboDrawWin::WndCreate

(

)

[virtual]

Creates the GUI Window

This function will be called from the same thread that runs the message loop. The default implementation does neither show nor activate the empty window. However the callback OnWindowCreated() gets executed directly after this function returns and right before the message loop starts and shall be used to show and/or activate the window.

Returns:

whether or not window could be created.

Note:

This method does neither show nor activate the window. That is job is done in the default implementation of OnWindowCreated().

If this function returns false then the calling thread will terminate by a handled runtime_error.

Reimplemented from mbo::MboWinMsgHandler.

virtual void mbo::MboDrawWin::WndClear

(

)

[virtual]

White fill the client area. This function is normally only called from the default OnWindoCreated() callback.

virtual void mbo::MboDrawWin::OnWindowCreated

(

)

[virtual]

Used to initialized the window (first drawing).

This method may of course be overwritten to perform tasks like calling WndSetTitle() or WndSetIcon(). The default implementation simply calls WndClear() when this function gets invoked and then shows and activates it.

Note:

If you override this method you must ensure that you active and show the window because otherwise you wouldn't be able to use it.

You cannot use OnThreadStart() callback to draw because it is called before the window has been created.

Reimplemented from mbo::MboWinMsgHandler.

virtual void mbo::MboDrawWin::OnButtonDown	(	UINT	nFlags,
		int	x,
		int	y
	)			[virtual]

Callback called when a mouse button is pressed.

Parameters:

	nFlags	Any combination of: MK_CONTROL Set if the ctrl key is down. MK_LBUTTON Set if the left mouse button was active. MK_MBUTTON Set if the middle mouse button was active. MK_RBUTTON Set if the right mouse button was active. MK_SHIFT Set if the shift key is down.
	x	x position of mouse
	y	y position of mouse

Note:

x and y are relative to the upper-left corner of the client area.

virtual void mbo::MboDrawWin::OnButtonDblClk	(	UINT	nFlags,
		int	x,
		int	y
	)			[virtual]

Callback called when a mouse button is double clicked.

Parameters:

	nFlags	Any combination of: MK_CONTROL Set if the ctrl key is down. MK_LBUTTON Set if the left mouse button was active. MK_MBUTTON Set if the middle mouse button was active. MK_RBUTTON Set if the right mouse button was active. MK_SHIFT Set if the shift key is down.
	x	x position of mouse
	y	y position of mouse

Note:

x and y are relative to the upper-left corner of the client area.

virtual void mbo::MboDrawWin::OnButtonUp	(	UINT	nFlags,
		int	x,
		int	y
	)			[virtual]

Callback called when a mouse button is release (up after pressed).

Parameters:

	nFlags	Any combination of: MK_CONTROL Set if the ctrl key is down. MK_LBUTTON Set if the left mouse button was active. MK_MBUTTON Set if the middle mouse button was active. MK_RBUTTON Set if the right mouse button was active. MK_SHIFT Set if the shift key is down.

	)			[virtual]

Overwrite this handler if you want to handle any message.

Note:

You should call ProcessDefault() from ProcessMessage() for any message not handled yourself.

Parameters:

	hwnd	Handle to the window procedure that received the message. This normally matches m_hwnd.
	uMsg	Specifies the message received.
	wParam	Specifies additional message information. The content of this parameter depends on the value of the Msg parameter.
