Detailed Description
A ruler widget.
The vertical ruler looks similar to this:
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.
For performance reasons, the public methods don't call TQWidget::repaint(). (Slots do, see documentation below.) All the changed settings will be painted once after leaving to the main event loop. For performance painting the slot methods should be used, they do a fast TQWidget::repaint() call after changing the values. For setting multiple values like minValue(), maxValue(), offset() etc. using the public methods is recommended so the widget will be painted only once when entering the main event loop.
A ruler widget.

Constructor & Destructor Documentation
◆ KRuler() [1/3]
KRuler::KRuler | ( | TQWidget * | parent = 0 , |
const char * | name = 0 |
||
) |
The style (or look) of the ruler.
Constructs a horizontal ruler.
Definition at line 94 of file kruler.cpp.
◆ KRuler() [2/3]
KRuler::KRuler | ( | Orientation | orient, |
TQWidget * | parent = 0 , |
||
const char * | name = 0 , |
||
WFlags | f = 0 |
||
) |
Constructs a ruler with orientation orient
.
parent
, name
and f
are passed to TQFrame. The default look is a raised widget but may be changed with the inherited TQFrame methods.
- Parameters
-
orient Orientation of the ruler. parent Will be handed over to TQFrame. name Will be handed over to TQFrame. f Will be handed over to TQFrame.
Definition at line 104 of file kruler.cpp.
◆ KRuler() [3/3]
KRuler::KRuler | ( | Orientation | orient, |
int | widgetWidth, | ||
TQWidget * | parent = 0 , |
||
const char * | name = 0 , |
||
WFlags | f = 0 |
||
) |
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
, name
and f
are passed to TQFrame.
- Parameters
-
orient Orientation of the ruler. widgetWidth Fixed width of the widget. parent Will be handed over to TQFrame. name Will be handed over to TQFrame. f Will be handed over to TQFrame.

◆ setBigMarkDistance()
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 224 of file kruler.cpp.
◆ setEndLabel()
void KRuler::setEndLabel | ( | const TQString & | label | ) |
Sets the label this is drawn at the beginning of the visible part of the ruler to label
.
Definition at line 360 of file kruler.cpp.
◆ setLength()
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 465 of file kruler.cpp.
◆ setLengthFixed()
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
-
fix fixes the length, if true
Definition at line 491 of file kruler.cpp.
◆ setLittleMarkDistance()
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 206 of file kruler.cpp.
◆ setMaxValue()
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.
Definition at line 172 of file kruler.cpp.
◆ setMediumMarkDistance()
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 215 of file kruler.cpp.
◆ setMinValue()
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.
Definition at line 163 of file kruler.cpp.
◆ setOffset()
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
-
offset Number of pixel to move the ruler up or left from the beginning
Definition at line 503 of file kruler.cpp.
◆ setPixelPerMark()
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 457 of file kruler.cpp.
◆ setRange()
void KRuler::setRange | ( | int | min, |
int | max | ||
) |
Sets minimum and maximum values of the ruler pointer.
This method calls update() so that the widget is painted after leaving to the main event loop.
Definition at line 181 of file kruler.cpp.
◆ setRulerMetricStyle()
void KRuler::setRulerMetricStyle | ( | KRuler::MetricStyle | style | ) |
Sets up the necessary tasks for the provided styles.
A convenience method.

count Number of pixel moving up or left relative to the previous position

This doesn't affect the position of the ruler pointer. Only the visible part of the ruler is moved.
- Parameters
-
count Number of pixel moving up or left relative to the previous position
