	DESCRIPTION


Almost every application uses some of common controls in its implementation. 
Users used to see these common controls and khow how to use them. 

This the primary reason why you usually don't want to change the look 
and functionality of existing controls too much. But sometimes even by slightly 
changing the appearance of a control you can achive good results in terms
of enhancing the feel and look of your application's user interface. 

We suggest the following new feature for common controls: every control
(generally speaking, any window) can be in normal or hot state. By definition,
window is in hot state when mouse cursor is over it or it has focus. Otherwise 
window is in normal state. Naturally, in order to distinguish window in 
different states some graphical effects should be applied. 
E.g. the drawing of window borders in different states might be different.

We call controls that support normal and hot state - cool controls.

We designed template class COXCoolCtrl that simplifies process of 
converting of common controls to cool ones.

COXCoolCtrl template has one argument that specifies the parent class 
of the new cool control. E.g. if you would like to design your own cool
listbox class you can declare it as following:

	class CCoolListBox : public COXCoolCtrl<CListBox>


While implementing cool control using COXCoolCtrl derivation you might would 
like to override the following protected virtual functions:


	virtual void OnChangeHotState(BOOL bInHotState);
	virtual void OnFocusChange(CWnd* pWndGainFocus, CWnd* pWndLooseFocus);
	virtual void OnMouseEnter(const CPoint& ptCursor);
	virtual void OnMouseLeave(const CPoint& ptCursor);
	virtual BOOL HandleKey(int nVirtKey);
	virtual BOOL OnChangeTooltipText(const CString& sTooltipText);


Refer to the class reference for detailed function explanations. 

Almost always you would like to override OnChangeHotState() function which is 
called when window is about to change its state from hot to normal and vise versa. 
n your implementation of this function you might redraw the window in order 
to show that window has changed its state.

OnFocusChange() is called every time window looses or gains focus and 
OnMouseEnter() and OnMouseLeave() functions are called every time mouse enters
or leaves the screen space taken by the window correspondingly.

HandleKey() function will be called every time when user presses any key down. 
Overriding this function you can handle pressed key before control has a chance 
to do that. By returning TRUE you will notify control that you handled the event
yourself and don't want to run default handler implementation.


One of the additional useful feature that COXCoolCtrl supports is tooltip 
for the control. You can set/retrieve tooltip text using the following functions:

	BOOL SetTooltipText(const CString& sTooltipText);
	BOOL GetTooltipText(CString& sTooltipText) const;


Every time you change the tooltip text OnChangeTooltipText() function will be called.
By overriding this function you can control the process of setting of tooltip text.
By returning FALSE you specify that you don't allow to change the tooltip text.


There are a few additional public functions that you might find useful:

	BOOL IsInHotState() const;
	BOOL IsMouseOver() const;

IsInHotState() function retrieves the flag that specifies whether the window is 
in hot or normal state. IsMouseOver() function retrieves the flag that specifies 
whether the current mouse position is over the window or not.

Although it's not a must requirement but it would be nice if control was able
to support standard and new cool state. By default when control is created of 
subclassed the existing one it is set to cool state. But calling the following 
function you can set it back to statndard state:

	virtual void SetCoolState(BOOL bCoolState);

You can retrieve the flag that specifies whether the control is in cool or 
normal state

	virtual BOOL IsInCoolState() const;

As you can see both of these functions are declared as virtual so if you don't want 
to support standard appearance of the control you might override this function 
(SetCoolState() would do nothing and IsInCoolState() would always return TRUE).



Again we would like to emphasize that COXCoolCtrl class is designed specifically 
in order to help you to create cool common controls. We are going to come up
with classes that implements some common controls as cool ones (take look at the 
COXCoolComboBox class which implements cool combobox).



================================================================================


								Cool Controls


Just as a reminder we assume that a common control can be called the "cool" one
if it can take normal or hot state. By definition, window is in hot state when 
mouse cursor is over it or it has focus. Otherwise window is in normal state. 
Naturally, in order to distinguish window in different states some graphical effects 
should be applied. E.g. the drawing of window borders in different states might be 
different.

COXCoolCtrl class is the basic class that is used to create cool controls. 
This is a template class and it can be easily used in order to create "cool" versions
of common controls. Actually our implementation of classes for cool common controls 
doesn't have any public functions, so it's strongly recommended to refer to 
COXCoolCtrl reference for the functionality available for all cool controls (e.g. 
all cool controls support tooltips).

When we were talking about implementation of "cool" versions of cool controls we 
mentioned that it didn't require too much job to be done because almost everything
is covered by COXCoolCtrl. Actually for the following common controls "cool" state
will be supported automatically if you use corresponding MFC class as 
template argument.

  Common Control		MFC	class			UTB class

  Edit control			CEdit				COXCoolCtrl<CEdit>
  Rich edit control		CRichEditCtrl		COXCoolCtrl<CRichEditCtrl>
  Tree view				CTreeCtrl			COXCoolCtrl<CTreeCtrl>
  List view				CListCtrl			COXCoolCtrl<CListCtrl>
  List box				CListBox			COXCoolCtrl<CListBox>
  Progress bar			CProgressCtrl		COXCoolCtrl<CProgressCtrl>
  Hot key control		CHotKeyCtrl			COXCoolCtrl<CHotKeyCtrl>
  Date-time picker		CDateTimeCtrl		COXCoolCtrl<CDateTimeCtrl>
  Month calendar		CMonthCalCtrl		COXCoolCtrl<CMonthCalCtrl>
  IP Address control	CIPAddressCtrl		COXCoolCtrl<CIPAddressCtrl>


For the other common controls we had to come up with new classes as long
as additional drawing routines have been required. Below you will find the list
of all such controls and the corresponding Ultimate Toolbox classes. 

  Common Control		MFC	class			UTB class

  Push button
  Check button			CButton				COXCoolButton
  Radio button controls
  Spin button			CSpinButtonCtrl		COXCoolSpinButtonCtrl
  Combo box				CComboBox			COXCoolComboBox
  Slider				CSliderCtrl			COXCoolSliderCtrl
  Scroll bar			CScrollBar			COXCoolScrollBar



We would like to emphasize again that these classes doesn't have any public functions
of their own. Refer to the COXCoolCtrl function reference for details on the 
functionality available for all cool controls.


All above mentioned classes can be used without any restrictions instead the
standard ones. Take look at the CoolControls sample that demonstrates the use
of all cool controls classes. This sample can be found in .\Samples\gui\CoolControls
