Detailed Description

The spinner control can be used to enter any positive or negative integer value either through the keyboard, the up/down spinner buttons or the mouse wheel when over the control.

After creating the spinner the user can set the initial value to display and the minimum and maximum permitted values. The user also specifies the increment/decrement value to apply when using the spinner buttons or mouse wheel to change the value.

When entering numbers from the keyboard the - key can be pressed at any time to negate the current value.

Member Function Documentation

◆ changeText()

boolean g4p_controls.GSpinner.changeText ( )
protected

Reimplemented from g4p_controls.GEditableTextControl.

◆ dec()

boolean g4p_controls.GSpinner.dec ( )

Decrement the current value. It will be constrained to the current range limits

Returns
true if the value changes

◆ draw()

void g4p_controls.GSpinner.draw ( )

Reimplemented from g4p_controls.GAbstractControl.

◆ getSnapshot()

PGraphics g4p_controls.GSpinner.getSnapshot ( )

This method should be used sparingly since it is heavy on resources.

Returns
a PGraphics object showing current state of the control (ignoring rotation)

Reimplemented from g4p_controls.GAbstractControl.

◆ getValue()

int g4p_controls.GSpinner.getValue ( )
Returns
the current value

◆ handleDec()

void g4p_controls.GSpinner.handleDec ( GButton  button,
GEvent  event 
)

Do not call this method instead use dec()
This method is used internally by the spinner button.

◆ handleInc()

void g4p_controls.GSpinner.handleInc ( GButton  button,
GEvent  event 
)

Do not call this method instead use inc()

◆ inc()

boolean g4p_controls.GSpinner.inc ( )

Increment the current value. It will be constrained to the current range limits

Returns
true if the value changes

◆ keyEvent()

void g4p_controls.GSpinner.keyEvent ( KeyEvent  e)

Reimplemented from g4p_controls.GEditableTextControl.

◆ keyPressedProcess()

void g4p_controls.GSpinner.keyPressedProcess ( int  keyCode,
char  keyChar,
boolean  shiftDown,
boolean  ctrlDown 
)
protected

Reimplemented from g4p_controls.GEditableTextControl.

◆ keyTypedProcess()

void g4p_controls.GSpinner.keyTypedProcess ( int  keyCode,
char  keyChar,
boolean  shiftDown,
boolean  ctrlDown 
)
protected

Reimplemented from g4p_controls.GEditableTextControl.

◆ loseFocus()

void g4p_controls.GSpinner.loseFocus ( GAbstractControl  grabber)
protected

Give up focus but if the text is only made from spaces then set it to null text.
Fire focus events for the GTextField and GTextArea controls

Reimplemented from g4p_controls.GEditableTextControl.

◆ mouseEvent()

void g4p_controls.GSpinner.mouseEvent ( MouseEvent  event)

Reimplemented from g4p_controls.GAbstractControl.

int  low,
int  high,
int  delta 
)

Set the limits for this spinner control.
The range limits are swapped if high &lt low
The initial value will be constrained to the range ≥ low and ≤ high.
The increment / decrement value will not be allowed to exceed the range i.e. high - low

Parameters
initthe initial value to display
lowthe lowest valid value
highthe highest valid value
deltathe inc/decrement value

◆ setStyledText()

void g4p_controls.GSpinner.setStyledText ( StyledString  ss)

This method is ignored for this control

Reimplemented from g4p_controls.GTextBase.

◆ setText()

void g4p_controls.GSpinner.setText ( String  text)

This method is ignored for this control

Reimplemented from g4p_controls.GTextBase.

◆ setValue()

void g4p_controls.GSpinner.setValue ( int  newValue)

Sets the current value to be displayed. It will be constrained to the current range limits.

Parameters
vthe new value to display

◆ updateBuffer()

void g4p_controls.GSpinner.updateBuffer ( )
protected

If the buffer is invalid then redraw it.

@TODO need to use palette for colours

Reimplemented from g4p_controls.GAbstractControl.
