TGNumberEntry, TGNumberEntryField and TGNumberFormat
TGNumberEntry is a number entry input widget with up/down buttons.
TGNumberEntryField is a number entry input widget.
TGNumberFormat contains enum types to specify the numeric format.
The number entry widget is based on TGTextEntry but allows only
numerical input. The widget support numerous formats including
integers, hex numbers, real numbers, fixed fraction reals and
time/date formats. The widget also allows to restrict input values
to non-negative or positive numbers and to specify explicit limits.
The following styles are supported:
kNESInteger: integer number
kNESRealOne: real number with one digit (no exponent)
kNESRealTwo: real number with two digits (no exponent)
kNESRealThree: real number with three digits (no exponent)
kNESRealFour: real number with four digits (no exponent)
kNESReal: arbitrary real number
kNESDegree: angle in degree:minutes:seconds format
kNESMinSec: time in minutes:seconds format
kNESHourMin: time in hour:minutes format
kNESHourMinSec: time in hour:minutes:seconds format
kNESDayMYear: date in day/month/year format
kNESMDayYear: date in month/day/year format
kNESHex: hex number
The following attributes can be specified:
kNEAAnyNumber: any number is allowed
kNEANonNegative: only non-negative numbers are allowed
kNEAPositive: only positive numbers are allowed
Explicit limits can be specified individually:
kNELNoLimits: no limits
kNELLimitMin: lower limit only
kNELLimitMax upper limit only
kNELLimitMinMax both lower and upper limits
TGNumberEntryField is a plain vanilla entry field, whereas
TGNumberEntry adds two small buttons to increase and decrease the
numerical value in the field. The number entry widgets also support
using the up and down cursor keys to change the numerical values.
The step size can be selected with control and shift keys:
-- small step (1 unit/factor of 3)
shift medium step (10 units/factor of 10)
control large step (100 units/factor of 30)
shift-control huge step (1000 units/factor of 100)
The steps are either linear or logarithmic. The default behaviour
is set when the entry field is created, but it can be changed by
pressing the alt key at the same time.
Changing the number in the widget will generate the event:
kC_TEXTENTRY, kTE_TEXTCHANGED, widget id, 0.
Hitting the enter key will generate:
kC_TEXTENTRY, kTE_ENTER, widget id, 0.
Hitting the tab key will generate:
kC_TEXTENTRY, kTE_TAB, widget id, 0.

: TGCompositeFrame(parent, 10 * wdigits, 25), fButtonToNum(kTRUE)
Constructs a numeric entry widget
~TGNumberEntry()
Destructs a numeric entry widget
void Associate(const TGWindow *w)
Make w the window that will receive the generated messages.
void SetLogStep(Bool_t on)
Set log steps
void SetState(Bool_t enable)
Set the active state
void SetButtonToNum(Bool_t state)
Send button messages to the number field (true) or parent widget (false).
When the message is sent to the parent widget, it is responsible to change
the numerical value accordingly. This can be useful to implement cursors
which move from data point to data point. For the message being sent
see ProcessMessage().
Bool_t ProcessMessage(Long_t msg, Long_t parm1, Long_t parm2)
Process the up/down button messages. If fButtonToNum is false the
following message is sent: kC_COMMAND, kCM_BUTTON, widget id, param
param % 100 is the step size
param % 10000 / 100 != 0 indicates log step
param / 10000 != 0 indicates button down
void ValueChanged(Long_t val)
Emit ValueChanged(Long_t) signal. This signal is emitted when
fButtonToNum is false. The val has the following meaning:
val % 100 is the step size
val % 10000 / 100 != 0 indicates log step
val / 10000 != 0 indicates button down
void ValueSet(Long_t val)
Emit ValueSet(Long_t) signal. This signal is emitted when the
number entry value is changed. The val has the following meaning:
val % 100 is the step size
val % 10000 / 100 != 0 indicates log step
val / 10000 != 0 indicates button down
void SavePrimitive(ofstream &out, Option_t *)
Save a number entry widget as a C++ statement(s) on output stream out.
