## Detailed Description

The TQStyleOption class specifies optional parameters for TQStyle functions.

Some TQStyle functions take an optional argument specifying extra information that is required for a paritical primitive or control. So that the TQStyle class can be extended, TQStyleOption is used to provide a variable-argument for these options.

The TQStyleOption class has constructors for each type of optional argument, and this set of constructors may be extended in future TQt releases. There are also corresponding access functions that return the optional arguments: these too may be extended.

For each constructor, you should refer to the documentation of the TQStyle functions to see the meaning of the arguments.

When calling TQStyle functions from your own widgets, you must only pass the default TQStyleOption or the argument that TQStyle is documented to accept. For example, if the function expects TQStyleOption(TQMenuItem *, int), passing TQStyleOption(TQMenuItem *) leaves the optional integer argument uninitialized.

When subclassing TQStyle, you must similarly only expect the default or documented arguments. The other arguments will have uninitialized values.

If you make your own TQStyle subclasses and your own widgets, you can make a subclass of TQStyleOption to pass additional arguments to your TQStyle subclass. You will need to cast the "const TQStyleOption&" argument to your subclass, so be sure your style has been called from your widget.

## Member Type Documentation

### TQStyleOption::StyleOptionDefault

This enum value can be passed as the optional argument to any TQStyle function.

- `TQStyleOption::Default`

## Member Function Documentation

### TQStyleOption::TQStyleOption ( StyleOptionDefault = Default )

The default option. This can always be passed as the optional argument to TQStyle functions.

### TQStyleOption::TQStyleOption ( int in1 )

Pass one integer, in1. For example, headerSection.

### TQStyleOption::TQStyleOption ( int in1, int in2 )

Pass two integers, in1 and in2. For example, linewidth and midlinewidth.

### TQStyleOption::TQStyleOption ( int in1, int in2, int in3, int in4 )

Pass four integers, in1, in2, in3 and in4.

### TQStyleOption::TQStyleOption ( TQMenuItem * m )

Pass a menu item, m.

### TQStyleOption::TQStyleOption ( TQMenuItem * m, int in1 )

Pass a menu item and an integer, m and in1.

### TQStyleOption::TQStyleOption ( TQMenuItem * m, int in1, int in2 )

Pass a menu item and two integers, m, in1 and in2.

### TQStyleOption::TQStyleOption ( const TQColor & c )

Pass a color, c.

### TQStyleOption::TQStyleOption ( TQTab * t )

Pass a TQTab, t.

### TQStyleOption::TQStyleOption ( TQListViewItem * i )

Pass a TQListViewItem, i.

### TQStyleOption::TQStyleOption ( TQCheckListItem * i )

Pass a TQCheckListItem, i.

### TQStyleOption::TQStyleOption ( TQt::ArrowType a )

Pass an TQt::ArrowType, a.

### TQStyleOption::TQStyleOption ( const TQRect & r )

Pass a TQRect, r.

### TQStyleOption::TQStyleOption ( TQWidget * w )

Pass a TQWidget, w.

### TQt::ArrowType TQStyleOption::arrowType () const

Returns an arrow type if the appropriate constructor was called; otherwise the return value is undefined.

### TQCheckListItem * TQStyleOption::checkListItem () const

Returns a check list item if the appropriate constructor was called; otherwise the return value is undefined.

### const TQColor & TQStyleOption::color () const

Returns a color if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::day () const

Returns the index of the day in the month if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::frameShadow () const

Returns a TQFrame::Shadow value if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::frameShape () const

Returns a TQFrame::Shape value if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::headerSection () const

Returns the header section if the appropriate constructor was called; otherwise the return value is undefined.

### bool TQStyleOption::isDefault () const

Returns TRUE if the option was constructed with the default constructor; otherwise returns FALSE.

### int TQStyleOption::lineWidth () const

Returns the line width if the appropriate constructor was called; otherwise the return value is undefined.

### TQListViewItem * TQStyleOption::listViewItem () const

Returns a TQListView item if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::maxIconWidth () const

Returns the maximum width of the menu item check area if the appropriate constructor was called; otherwise the return value is undefined.

### TQMenuItem * TQStyleOption::menuItem () const

Returns a menu item if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::midLineWidth () const

Returns the mid-line width if the appropriate constructor was called; otherwise the return value is undefined.

### TQRect TQStyleOption::rect () const

Returns a rectangle if the appropriate constructor was called; otherwise the return value is undefined.

### TQTab * TQStyleOption::tab () const

Returns a TQTabBar tab if the appropriate constructor was called; otherwise the return value is undefined.

### int TQStyleOption::tabWidth () const

Returns the tab indent width if the appropriate constructor was called; otherwise the return value is undefined.

### TQWidget * TQStyleOption::widget () const

Returns a pointer to a widget if the appropriate constructor was called; otherwise the return value is undefined.
