Detailed Description

A wrapper around KisIntParseSpinBox, which is a cleverer SpinBox, able to parse arithmetic expressions. The widget itself is accessed with the widget() function.

Use this spinbox instead of the basic one from Qt if you want it to be able to parse arithmetic expressions.

Member Function Documentation

errorWhileParsing

void IntParseSpinBox::errorWhileParsing ( const QString & expr ) const

signal

signal emitted when the last parsed expression is not valid.

isLastValid

bool IntParseSpinBox::isLastValid ( ) const

slot

Get if the last expression entered is a valid one.

Return values

true	if the last expression entered is valid
false	otherwise

Definition at line 47 of file IntParseSpinBox.cpp.

{
    return d->widget->isLastValid();
}

References d, KisIntParseSpinBox::isLastValid(), and krita::IntParseSpinBox::Private::widget.

noMoreParsingError

void IntParseSpinBox::noMoreParsingError ( ) const

signal

signal emitted when the last parsed expression is valid and the expression before was not valid.

setValue

void IntParseSpinBox::setValue ( int value, bool overwriteExpression = false )

slot

Set the value of the spinbox.

This reimplementation also tries to clear the current expression and warning message whenever possible. This will happen when the new value is different from the current one and the line edit has not the focus or it is read-only. One can force the reset also by passing true to the overwriteExpression parameter.

Parameters

value	The new value
overwriteExpression	Get if the expression in the edit field (and the warning message) should be reset to reflect the new value. The default is false so that if the user is editing the expression it won't be disrupted by any default call to this function

Definition at line 42 of file IntParseSpinBox.cpp.

{
    d->widget->setValue(value, overwriteExpression);
}

References d, KisIntParseSpinBox::setValue(), value(), and krita::IntParseSpinBox::Private::widget.

stepBy

void IntParseSpinBox::stepBy ( int steps )

slot

This is a reimplementation of QSpinBox::stepBy that uses setValue.

Parameters

steps

Number of steps that the value should change

Definition at line 37 of file IntParseSpinBox.cpp.

{
    d->widget->stepBy(steps);
}

veryCleanText

QString IntParseSpinBox::veryCleanText ( ) const

virtualslot

This virtual function is similar to cleanText(). But child classes may reimplement it to further process ("clean up") the expression.

Returns

The processed expression

Definition at line 52 of file IntParseSpinBox.cpp.

{
    return d->widget->veryCleanText();
}

References d, KisIntParseSpinBox::veryCleanText(), and krita::IntParseSpinBox::Private::widget.

widget

QSpinBox * IntParseSpinBox::widget ( ) const

slot

Get the internal KisIntParseSpinBox as a QWidget, so it may be added to a UI.

Returns

the internal KisIntParseSpinBox as a QWidget

Definition at line 32 of file IntParseSpinBox.cpp.

{
    return d->widget;
}
