Detailed Description

Custom spin box.

The QDoubleSpinBox is used for both integer and float values instead of using QSpinBox as a base for the former. This is done to keep the code concise. All internal values will be handled as floats and only textFromValue() makes a difference.

The LCDSpinBox::Kind was introduced to handle custom constraints for the widgets concerning with the pattern size in the PatternEditorPanel.

Updating the font family in QDoubleSpinBox is not supported and changing the font size (both via setFont()) yields erratic results.

Member Enumeration Documentation

◆ Kind

enum class Kind

strong

Enumerator

Default

Behaves like QDoubleSpinBox.

PatternSizeNumerator

The minimum value - a fractional one - can only be reached by entering it using the keyboard.

up/down keys as well as mouse wheel increment the number by one and will stay at integer values per default.

PatternSizeDenominator

Only a limited number of values is allowed.
