MiscSliderField |
Inherits From: | TextField : Control : View : Responder : Object | |
Declared In: | MiscSliderField.h |
Class Description |
A MiscSliderField is a simple subclass of TextField that uses a MiscSliderCell inside itself and implements methods to
pass the new configuration information and requests through to the cell. This allows a matching API when
communicating with both a MiscSliderField and a MiscSliderCell in a Matrix (for example). A MiscStringArray or a
StringList (found as a MiniExample) can be attached to provide text strings that get shown instead of numbers.
A valid string list object responds to: |

Instance Methods |
expandMax |
-(BOOL) expandMax |
Returns YES if maxBoundary is in effect stopping the arrow buttons from reaching maxValue.
See also: - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
expandMin |
-(BOOL) expandMin |
Returns YES if minBoundary is in effect stopping the arrow buttons from reaching minValue.
See also: - expandMax, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
initFrame: |
- initFrame:(const NXRect *)frame |
Initializes and returns the receiver with a MiscSliderCell inside it. Returns self.
integerOnly |
-(BOOL) integerOnly |
Returns YES if the MiscSliderCell is displaying only integral values.
See also: - setIntegerOnly:
maxBoundary |
-(double) maxBoundary |
Returns the current limit that the value will stop at when the up arrow button is being used to change the value. This
limit can be changed by entering a larger value using the keyboard. This limit will be set the highest value entered that
is still within the bounds of maxValue. It cannot be reduced except programmatically.
See also: - expandMax, - expandMin, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
maxValue |
-(double) maxValue |
Returns the highest value this field is allowed to reach. This limit cannot be exceeded in any way. maxBoundary can
match this value and then have no effect.
See also: - expandMax, - expandMin, - maxBoundary, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
minBoundary |
-(double) minBoundary |
Returns the current limit that the value will stop at when the down arrow button is being used to change the value. This
limit can be changed by entering a smaller value using the keyboard. This limit will be set the lowest value entered
that is still within the bounds of minValue. It cannot be increased except programmatically.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
minValue |
-(double) minValue |
Returns the lowest value this field is allowed to reach. This value cannot be exceeded in any way. minBoundary can
match this value and then have no effect.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
position |
-(int) | position |
Returns the position of the TextFieldCell relative to the SliderCell. See setPosition: for the values.
See also: - setPosition:, - setSplit:, - split
setExpandMax: |
- setExpandMax:(BOOL)flag |
If flag is YES then maxBoundary has an effect on the upper limit of the field value when it's adjusted with the arrow
buttons. Returns self.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
setExpandMin: |
- setExpandMin:(BOOL)flag |
If flag is YES then minBoundary has an effect on the lower limit of the field value when it's adjusted with the arrow
buttons. Returns self.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setMaxBoundary, - setMaxValue, - setMinBoundary, - setMinValue
setIntegerOnly |
- setIntegerOnly:(BOOL)flag |
If flag is YES only the integral part of the value will be used. The fractional part of the value is truncated when the
value is set, doubleValue will return the same value as intValue when this flag is set to YES. Returns self.
See also: - integerOnly
setMaxBoundary |
- setMaxBoundary:(double)value |
Sets the highest value the field will allow when using the arrow buttons to adjust the value. This value can be
exceeded and altered by typing a value greater than this limit. This value will be adjusted to match the entered amount
with an additional limitation that it will stop at maxValue. Returns self.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxValue, - setMinBoundary, - setMinValue
setMaxValue |
- setMaxValue:(double)value |
Sets the highest value the field will allow. There is no way to exceed this limit from the interface. maxBoundary will
stop expanding when it gets to this value. Returns self.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMinBoundary, - setMinValue
setMinBoundary |
- setMinBoundary:(double)value |
Sets the lowest value the field will allow when using the arrow buttons to adjust the value. This value can be exceeded
and altered by typing a value lower than this limit. This value will be adjusted to match the entered amount with an
additional limitation that it will stop at minValue. Returns self.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinValue
setMinValue |
- setMinValue:(double)value |
Sets the lowest value the field will allow. There is no way to exceed this limit from the interface. minBoundary will
stop expanding when it gets to this value. Returns self.
See also: - expandMax, - expandMin, - maxBoundary, - maxValue, - minBoundary, - minValue, - setExpandMax, - setExpandMin, - setMaxBoundary, - setMaxValue, - setMinBoundary
setPosition |
- setPosition:(int)where |
Sets the position of the TextFieldCell relative to the SliderCell. Constants are defined in MiscSliderCell.h and can be
selected from MSC_ABOVELEFT, MSC_ABOVECENTER, MSC_ABOVERIGHT, MSC_LEFT, MSC_RIGHT,
MSC_BELOWLEFT, MSC_BELOWCENTER and MSC_BELOWRIGHT. See setSplit: for further control of the
display. Returns self.
See also: - position, - setSplit:, - split
setSplit |
- setSplit:(int)percent |
Sets the width of the TextFieldCell as a percentage of the width of the entire MiscSliderCell. When the position is set
to MSC_LEFT or MSC_RIGHT the SliderCell is adjusted to take up the remaining horizontal space. In all the other
position settings the SliderCell takes the full width of the MiscSliderCell and the TextFieldCell is still sized as a
percentage of the total length and positioned appropriately. Valid values are 0-100 but the minimum size of both the
TextFieldCell and the SliderCell are set. Returns self.
See also: - position, - setPosition:, - split
setStringList: |
- setStringList:anObject |
Sets the object to be asked for display strings. anObject should respond to stringAt: and count messages. When a
string list is set the range limits are all ignored and the cell is set to non-editable. The value of the cell will only fit
within a range defined by anObject's count method. Returns self.
anObject's stringAt: method should take an int as its argument and return a char * with the correct string to be displayed for the given value. The value of the argument will range from 0 to count - 1. This arrangement has been created to allow the MiscSliderField to be connected to a MiscStringArray or a StringList (found in the MiniExamples) object in Interface Builder so lists may be created, displayed and dealt with with no additional code. See also: - stringList
split |
-(int) | split |
Returns the relative width of the TextFieldCell in relation to the size of the MiscSliderCell.
See also: - position, - setPosition:, - setSplit:
stringList |
- stringList |
Returns the object that is taking the task of providing the display strings.
