Widget for entering bitcoin amounts.
bool validate()
Perform input validation, mark field as invalid if entered value is not valid.
void setReadOnly(bool fReadOnly)
Make read-only.
QSpinBox that uses fixed-point numbers internally and uses our own formatting/parsing functions...
QWidget * setupTabChain(QWidget *prev)
Qt messes up the tab chain by default in some cases (issue https://bugreports.qt-project.org/browse/QTBUG-10907), in these cases we have to set it up manually.
bool eventFilter(QObject *object, QEvent *event)
Intercept focus-in event and &#39;,&#39; key presses.
BitcoinAmountField(QWidget *parent=nullptr)
int64_t CAmount
Amount in satoshis (Can be negative)
Definition: amount.h:12
AmountSpinBox * amount
void setEnabled(bool fEnabled)
Enable/Disable.
void SetMinValue(const CAmount &value)
Set the minimum value in satoshis.
void setSingleStep(const CAmount &step)
Set single step in satoshis.
QValueComboBox * unit
void clear()
Make field empty and ready for new input.
void setValid(bool valid)
Mark current value as invalid in UI.
void SetMaxValue(const CAmount &value)
Set the maximum value in satoshis.
void setDisplayUnit(int unit)
Change unit used to display amount.
void setValue(const CAmount &value)
void SetAllowEmpty(bool allow)
If allow empty is set to false the field will be set to the minimum allowed value if left empty...
