Detailed Description

template<class EventHandlerClass, class MessageMapPolicy>
class SmartWin::WidgetComboBox< EventHandlerClass, MessageMapPolicy >

You can either inherit from this class or add an instance of this class into your WidgetWindow inherited class.
If you inherit from the class you should explicitly call create e.g. in the CTOR of you class.
If you instantiate it directly (through the class Widget) you should create it by calling WidgetFactory::createxxx where xxx equals the name of the class WITHOUT the Widget part.

Member Function Documentation

void addRemoveExStyle	(	DWORD	addStyle,
		bool	add
	)			`[inherited]`

Use this function to add or remove windows exStyles.

The first parameter is the type of style you wish to add/remove.
The second argument is a boolean indicating if you wish to add or remove the style (if true add style, else remove)

void addRemoveStyle	(	DWORD	addStyle,
		bool	add
	)			`[inherited]`

Use this function to add or remove windows styles.

The first parameter is the type of style you wish to add/remove.
The second argument is a boolean indicating if you wish to add or remove the style (if true add style, else remove)

int addValue ( const SmartUtil::tstring & val )

Appends a value to the ComboBox.

The return value is the index of the new item appended.

void bringToBottom ( ) [inherited]

Brings the widget to the bottom.

Makes the widget become the bottom most widget meaning it will be obscured by all other widgets which are contained in the same container widget.
For instance if you have two widgets which partially hides eachother and you call bringToBottom on one of them it will make sure that the widget you call bringToBottom on will be the one which will be invisible and the other one will be all visible by the parts which are obscured by the this widget.

void bringToFront ( ) [inherited]

Brings the widget to the front.

Makes the widget become the front most widget meaning it will not be obscured by other widgets which are contained in the same container widget.
For instance if you have two widgets which partially hides eachother and you call bringToFront on one of them it will make sure that the widget you call bringToFront on will be the one which will be all visible and the other one will be partially hidden by the parts which are obscured by the this widget.

void create ( const Seed & cs = getDefaultSeed() ) [virtual]

Actually creates the ComboBox Control.

You should call WidgetFactory::createComboBox if you instantiate class directly.
Only if you DERIVE from class you should call this function directly.

Utilities::Thread fork ( unsigned long(EventHandlerClass::*)() threadProc ) [inherited]

Creates a new thread on the given function.

Forks execution into a member function. If you wish to later manipulate the thread in some way use the Utilities::Thread class to store the return value of this function.

Utilities::Thread fork	(	const Param &	par,
		unsigned long(EventHandlerClass::*)(Param &)	threadProc
	)			`[inherited]`

Creates a new thread and passes the given parameter.

Forks execution into a member function with the given parameter of the given type. If you wish to later manipulate the thread in some way use the Utilities::Thread class to store the return value of this function.

Rectangle getBounds ( ) const [inherited]

Returns the position and size of the window.

Note that this is in screen coordinates meaning the position returned is relative to the upper left corner of the desktop screen, the function also returns in the size member of the Rectangle the size of the window and not the position of the lower right point. Values includes borders, frames and toolbar etc of the window.

bool getCapsLockOn ( ) [inherited]

Checks if Caps Lock is on.

Use this function if you need to determine if Caps Lock is ON

Point getClientAreaSize ( ) const [inherited]

Returns the size of the client area of the window.

This differs from getSize because it disregards the border and headers, this function only returns the client area of the Widget meaning the area which it is possible to draw on.

bool getControlPressed ( ) [inherited]

Checks if control is pressed.

Use this function if you need to determine if any of the CTRL keys are pressed.

int getCount ( )

Returns the number of items present in the ComboBox.

Utilities::CriticalSection & getCriticalSection ( ) [inherited]

Returns a CriticalSection associated with the current Widget object.

If you need serialized thread safe access to the Widget call this function and either stuff the returned object into a Utilities::ThreadLock or call Utilities::CriticalSection::lock (then you manually have to ensure CriticalSection::unlock is called on it)

HMENU getCtrlId ( ) const [inherited]

Returns the control id of the Widget.

This one only makes sense for control items, e.g. WidgetButton, WidgetComboBox etc.
Every control in a Widget has got its own control ID, mark that for a WidgetWindow this will always be ZERO

Point getDesktopSize ( ) [static, inherited]

Returns the screen size.

This is the screen size, and useful for making applications that must adapt to different screen sizes.

bool getEnabled ( ) const [inherited]

Retrieves the enabled property of the Widget.

Use this function to check if the Widget is Enabled or not. If the Widget is enabled this function will return true.

bool getFocus ( ) const [inherited]

Retrieves the focus property of the Widget.

Use this function to check if the Widget has focus or not. If the Widget has focus this function will return true.

FontPtr getFont ( ) [inherited]

Returns the font used by the Widget.

Returns the Font object currently being used by the Widget

Widget* getParent ( ) const [inherited]

Returns the parent Widget of the Widget.

Most Widgets have got a parent, this function will retrieve a pointer to the Widgets parent, if the Widget doesn't have a parent it will return a null pointer.

Point getPosition ( ) const [inherited]

Returns the position of the window.

Note that this is in screen coordinates meaning the position returned is relative to the upper left corner of the desktop screen.

Reimplemented in WidgetProgressBar, and WidgetSlider.

int getSelectedIndex ( ) const [virtual]

Return the selected index of the Widget.

The return value is the selected items index of the Widget, if no item is selected the return value will be -1.
Note!
Some Widgets have the possibillity of selecting multiple items, if so you should not use this function but rather the multiple selection value getter.

Implements AspectSelection.

SmartUtil::tstring getSelectedValue ( )

Return the selected value of the ComboBox.

If no item is actually selected the return value is "".

bool getShiftPressed ( ) [inherited]

Checks if shift is pressed.

Use this function if you need to determine if any of the SHIFT keys are pressed.

Point getSize ( ) const [inherited]

Returns the size of the window.

Includes the border, frame and toolbar etc of the window.

Point getTextSize ( const SmartUtil::tstring & text ) [inherited]

Fills a Point with the size of text to be drawn in the Widget's font.

getTextSize determines the height and width that text will take.
This is useful if you want to allocate enough space to fit known text.
It accounts for the set font too.

SmartUtil::tstring getValue ( int index )

ComboBox.

Returns the string of the ComboBox at the given index.
Possible indices are [0.. getCount() - 1]

bool getVisible ( ) const [inherited]

Retrieves the visible property of the Widget.

Use this function to check if the Widget is visible or not.
If the Widget is visible this function will return true.

HWND handle ( ) const [inherited]

Returns the HWND to the Widget.

Returns the HWND to the inner window of the Widget.
If you need to do directly manipulation of the window use this function to retrieve the HWND of the Widget.

void invalidateWidget ( ) [inherited]

Add this widget to the update area.

Same as updateWidget except that this does not force an immediate redraw.

void maximize ( ) [inherited]

Maximize your window.

This will make the window fill the whole area that the window has available.
This function cannot be called for any Widget types other than those derived from WidgetWindowBase.

void minimize ( ) [inherited]

Minimize your window.

This will make the window become minimized.
This function cannot be called for any Widget types other than those derived from WidgetWindowBase.

void onMiddleMouseDown ( typename MessageMapType::voidFunctionTakingMouseEventResult eventHandler ) [inherited]

Middle mouse button pressed event handler setter.

If supplied, function will be called when user press the Middle Mouse button in the client area of the widget.
The parameter passed is const MouseEventResult & which contains the state of the mouse.

void onRaw	(	typename MessageMapType::itsHresultFunctionTakingLparamWparam	eventHandler,
		const Message &	msg
	)			`[inherited]`

Setting the member event handler for a "raw" event.

Sets the event handler for the "raw" event handler. Use this if any of the predefined Event Handlers are not powerful enough or if you can't find the specific Event Handler you need.
Note!
This works in a special way. Unless you add the same Message twice, it will add that Event Handler and not remove the previous one. You can have "multiple" raw Event Handlers as long as the Message is not the same!
Note also!
This is an UNTYPED Event!
If there are other events which will handle the message, USE THOSE instead of this one!!!
This is a "last resort" event type.
Two parameters are passed: LPARAM and WPARAM
Return value is HRESULT which will be passed on to the System

void removeAllItems ( )

Removes all items from the ComboBox.

After this call there will be zero items in the ComboBox.

void restore ( ) [inherited]

Restores your window.

This will make the window become restored.
This function cannot be called for any Widget types other than those derived from WidgetWindowBase.

LRESULT sendWidgetMessage	(	HWND	hWnd,
		UINT	msg,
		WPARAM &	wPar,
		LPARAM &	lPar
	)			`[virtual]`

Send a message to the Widget.

If you need to be able to send a message to a Widget then use this function as it will unroll into
a SendMessage from the Windows API

Reimplemented from MessageMapControl.

void setBounds	(	int	x,
		int	y,
		int	width,
		int	height,
		bool	updateWindow = `true`
	)			`[inherited]`

Sets the new size and position of the window.

x is the new horizontal position of your window.
y is the new vertical position of your window.
width is the new width and height is the new height of your window.
Zenith is as in all other bounds function top/left.
A call to this function will (probably) also MOVE your Widget too.

void setBounds	(	const Point &	newPos,
		const Point &	newSize,
		bool	updateWindow = `true`
	)			`[inherited]`

Sets the new size and position of the window.

The input parameter newPos of type Point defines the new position of the window.
The newSize member of type Point is the new size of the window.
A call to this function will (probably) also MOVE your Widget too.

void setBounds	(	const Rectangle &	rect,
		bool	updateWindow = `true`
	)			`[inherited]`

Sets the new size and position of the window.

The input parameter Rectangle defines the new size (and position) of the window.
The pos member of the Rectangle is the position and the size member is the size.
So a call to this function will (probably) also MOVE your Widget too.

void setEnabled ( bool enabled ) [inherited]

Sets the enabled property of the Widget.

Changes the enabled property of the Widget. Use this function to change the enabled property of the Widget

void setFocus ( ) [inherited]

Gives the Widget the keyboard focus.

Changes the font of the Widget to the given font. Use the class Font to construct a font in which to set by this function.

void setPositionPerPlace ( SmartWin::Place & bound ) [inherited]

Given a bounding Place class, place this Widget and adjust to the next position.

This function places the Widget into the bounding rectangle specified by bound.
The size of the Widget is preserved.
The Widgets are sized and placed from left to right until a row is full, and then continues with the next row.
The internal position of bound is updated.

void setSelectedIndex ( int idx ) [virtual]

Sets the selected index of the Widget.

The idx parameter is the (zero indexed) value of the item to set as the selected item. You must add the items before you set the selected index.

Implements AspectSelection.

void setSizeAsCol	(	const Rectangle &	rect,
		int	rows,
		int	rownum,
		int	border = `0`,
		bool	updateWindow = `true`
	)			`[inherited]`

Given a bounding rectangle with rows, put this Widget in the rownum position.

The rect defines a column made up of a number of rows. The rownum specifies a zero based index of the row to place the Widget. [ row0 ]
[ row1 ]
...
[ rownum ]
[ ]

Of course you could just generate a new bounding rectangle, but this is easier.

void setSizeAsGridPerPlace	(	SmartWin::Place &	bound,
		int	rows,
		int	cols
	)			`[inherited]`

this Widget in the next cell.

Bound determines the bounding rectangle, and borders.
rows and cols determine the size and position of each cell.
The internal position of bound is updated.
The Widgets are sized and placed according to the current cell, from left to right until a row is full, and then continues with the next row.

void setSizeAsRow	(	const Rectangle &	rect,
		int	cols,
		int	colnum,
		int	border = `0`,
		bool	updateWindow = `true`
	)			`[inherited]`

Given a bounding rectangle with cols, put this Widget in the colnum position.

The rect defines a row made up of a number of columns. The colnum specifies a zero based index of the column to place the Widget.
[ col0 ] [ col1 ] ... [ colnum ] [ ] [ ]

void setSizePerTextPerPlace	(	SmartWin::Place &	bound,
		const SmartUtil::tstring &	text,
		int	extraX = `0`,
		int	extraY = `0`
	)			`[inherited]`

Place after sizing for the Widget's text, and adjust to the next position.

This function places the Widget into the bounding rectangle specified by bound.
The idea is that the size of certain Widgets should really be large enough to show their text. Buttons and text areas are examples.
The size of the Widget is calculated from the size of getText().
It is optionally adjusted by the extraX and extraY.
The Widgets are sized and placed from left to right until a row is full, and then continues with the next row.
The internal position of bound is updated.

void setVisible ( bool visible ) [inherited]

Sets the visibility property of the Widget.

Changes the visibility property of the Widget.
Use this function to change the visibility property of the Widget

void subclass ( unsigned id ) [virtual, inherited]

Subclasses the dialog item with the given dialog item id.

Subclasses a dialog item, the id is the dialog item id from the resource editor.
Should normally not be called directly but rather called from e.g. one of the creational functions found in the WidgetFactory class.

void updateWidget ( ) [inherited]

Repaints the whole window.

Invalidate the window and repaints it.

char virtualKeyToChar ( int vkey ) [static, inherited]

Get ascii character from a Virtual Key.

Use this to convert from the input to the response to onKeyPressed to a character.
Virtual Keys do not take into account the shift status of the keyboard, and always report UPPERCASE letters.
