Detailed Description

A ruler widget.

The vertical ruler looks similar to this:

meters inches
------ <--- end mark ---> ------
-- -
-- <---little mark---> --
-- -
-- ---
--- <---medium mark -
-- --
-- tiny mark----> -
-- ----
-- -
---- <-----big mark --
-- -
|>-- <--ruler pointer--> |>--

There are tiny marks, little marks, medium marks, and big marks along the ruler.

To receive mouse clicks or mouse moves, the class has to be overloaded.

Constructor & Destructor Documentation

KRuler::KRuler ( QWidget parent = nullptr)
explicit

Constructs a horizontal ruler.

Definition at line 98 of file kruler.cpp.

KRuler::KRuler ( Qt::Orientation  orient,
QWidget parent = nullptr,
Qt::WindowFlags  f = Qt::WindowFlags() 
)
explicit

Constructs a ruler with orientation orient.

parent and f are passed to QFrame. The default look is a raised widget but may be changed with the inherited QFrame methods.

Parameters
orientOrientation of the ruler.
parentWill be handed over to QFrame.

KRuler::KRuler ( Qt::Orientation  orient,
int  widgetWidth,
QWidget parent = nullptr,
Qt::WindowFlags  f = Qt::WindowFlags() 
)

Constructs a ruler with orientation orient and initial width widgetWidth.

The width sets the fixed width of the widget. This is useful if you want to draw the ruler bigger or smaller than the default size. Note: The size of the marks doesn't change. parent and f are passed to QFrame.

Parameters
orientOrientation of the ruler.
widgetWidthFixed width of the widget.
parentWill be handed over to QFrame.
fWill be handed over to QFrame.

Member Function Documentation

int KRuler::bigMarkDistance ( ) const

Returns the distance between big marks.

int KRuler::littleMarkDistance ( ) const

Returns the distance between little marks.

int KRuler::maxValue ( ) const

Returns the maximal value of the ruler pointer.

Deprecated:
Since 5.0, use maximum().

Definition at line 195 of file kruler.cpp.

int KRuler::minValue ( ) const

Returns the minimal value of the ruler pointer.

Deprecated:
Since 5.0, use minimum().

Definition at line 179 of file kruler.cpp.

int KRuler::offset ( ) const

Returns the current ruler offset.

double KRuler::pixelPerMark ( ) const

Returns the number of pixels between two base marks.

void KRuler::setBigMarkDistance ( int  dist)

Sets distance between big marks.

For English (inches) or metric styles it is twice the medium mark distance.

Definition at line 247 of file kruler.cpp.

void KRuler::setEndLabel ( const QString label)

Sets the label this is drawn at the beginning of the visible part of the ruler to label.

Definition at line 374 of file kruler.cpp.

void KRuler::setFrameStyle ( int  )

Is a no-op.

Deprecated:
Since 5.0.

Definition at line 353 of file kruler.cpp.

void KRuler::setLength ( int  length)

Sets the length of the ruler, i.e.

the difference between the begin mark and the end mark of the ruler.

Same as (width() - offset())

when the length is not locked, it gets adjusted with the length of the widget.

Definition at line 485 of file kruler.cpp.

void KRuler::setLengthFixed ( bool  fix)

Locks the length of the ruler, i.e.

the difference between the two end marks doesn't change when the widget is resized.

Parameters
fixfixes the length, if true

Definition at line 509 of file kruler.cpp.

void KRuler::setLittleMarkDistance ( int  dist)

Sets the distance between little marks.

The default value is 1 in the metric system and 2 in the English (inches) system.

Definition at line 217 of file kruler.cpp.

void KRuler::setMaxValue ( int  value)

Sets the maximum value of the ruler pointer (default is 100).

This method calls update() so that the widget is painted after leaving to the main event loop.

Deprecated:
Since 5.0, use setMaximum().

Definition at line 187 of file kruler.cpp.

void KRuler::setMediumMarkDistance ( int  dist)

Sets the distance between medium marks.

For English (inches) styles it defaults to twice the little mark distance. For metric styles it defaults to five times the little mark distance.

Definition at line 232 of file kruler.cpp.

void KRuler::setMinValue ( int  value)

Sets the minimal value of the ruler pointer (default is 0).

This method calls update() so that the widget is painted after leaving to the main event loop.

Deprecated:
Since 5.0, use setMinimum(int).

Definition at line 171 of file kruler.cpp.

void KRuler::setOffset ( int  offset)

Sets the ruler slide offset.

This is like slideup() or slidedown() with an absolute offset from the start of the ruler.

Parameters
offsetNumber of pixel to move the ruler up or left from the beginning

Definition at line 521 of file kruler.cpp.

void KRuler::setPixelPerMark ( double  rate)

Sets the number of pixels between two base marks.

Calling this method stretches or shrinks your ruler.

For pixel display ( MetricStyle) the value is 10.0 marks per pixel ;-) For English (inches) it is 9.0, and for centimetres ~2.835 -> 3.0 . If you want to magnify your part of display, you have to adjust the mark distance here. Notice: The double type is only supported to give the possibility of having some double values. It should be used with care. Using values below 10.0 shows visible jumps of markpositions (e.g. 2.345). Using whole numbers is highly recommended. To use int values use setPixelPerMark((int)your_int_value); default: 1 mark per 10 pixels

Definition at line 471 of file kruler.cpp.

void KRuler::setRulerMetricStyle ( KRuler::MetricStyle  style)

Sets up the necessary tasks for the provided styles.

A convenience method.

Definition at line 394 of file kruler.cpp.

void KRuler::setShowBigMarks ( bool  show)

Shows/hides big marks.

Definition at line 307 of file kruler.cpp.

void KRuler::setShowEndLabel ( bool  show)

Show/hide number values of the end marks.

Default is false.

Definition at line 359 of file kruler.cpp.

void KRuler::setShowEndMarks ( bool  show)

Shows/hides end marks.

Definition at line 322 of file kruler.cpp.

void KRuler::setShowLittleMarks ( bool  show)

Shows/hides little marks.

Definition at line 277 of file kruler.cpp.

void KRuler::setShowMediumMarks ( bool  show)

Shows/hides medium marks.

Definition at line 292 of file kruler.cpp.

void KRuler::setShowPointer ( bool  show)

Shows/hides the pointer.

Definition at line 337 of file kruler.cpp.

void KRuler::setShowTinyMarks ( bool  show)

Shows/hides tiny marks.

Definition at line 262 of file kruler.cpp.

void KRuler::setTinyMarkDistance ( int  dist)

Sets the distance between tiny marks.

This is mostly used in the English system (inches) with distance of 1.

Definition at line 202 of file kruler.cpp.

void KRuler::slideDown ( int  count = 1)

Sets the number of pixels by which the ruler may slide down or right.

The number of pixels moved is realive to the previous position. The Method makes sense for updating a ruler, which is working with a scrollbar.

This doesn't affect the position of the ruler pointer. Only the visible part of the ruler is moved.

Parameters
countNumber of pixel moving up or left relative to the previous position

Definition at line 555 of file kruler.cpp.

void KRuler::slideUp ( int  count = 1)

Sets the number of pixels by which the ruler may slide up or left.

The number of pixels moved is realive to the previous position. The Method makes sense for updating a ruler, which is working with a scrollbar.

This doesn't affect the position of the ruler pointer. Only the visible part of the ruler is moved.

Parameters
countNumber of pixel moving up or left relative to the previous position

Definition at line 546 of file kruler.cpp.

void KRuler::slotNewOffset ( int  _offset)
slot

Sets the ruler marks to a new position.

The pointer is NOT updated. QWidget::repaint() is called afterwards.

Definition at line 589 of file kruler.cpp.

void KRuler::slotNewValue ( int  _value)
slot

Sets the pointer to a new position.

The offset is NOT updated. QWidget::repaint() is called afterwards.

Definition at line 564 of file kruler.cpp.

int KRuler::tinyMarkDistance ( ) const

Returns the distance between tiny marks.
