EditField derived classes

Widgets editing values in text representation are based on EditField and appropriate Convert class. Majority of them are defined using simple EditValue, EditMinMax and EditMinMaxNotNull template classes:

class EditValue : public EditField, public Cv

This class provides composition of EditField and specific Convert class. The advantage of deriving from Convert is that all Convert setup methods (like setting min/max value) are directly available without using further glue code.

EditValue& operator=(const DataType& t)

This helper operator allows direct assignment of value type to the editor.

This helper operator allows direct retrieval of value type from the editor.

Constructor assigns Convert class (in fact, *this) as the EditField converter.

class EditMinMax : public EditValue<DataType, Cv> 

Wrapper class for converters providing Min, Max and NotNull properties.

EditMinMax& operator=(const DataType& t)

This helper operator allows direct assignment of value type to the editor.

Default constructor.

This constructor sets Min and Max properties.

EditMinMax& Min(DataType min)

EditMinMax& Max(DataType max)

EditMinMax& NotNull(bool nn = true)

Sets Min, Max and NotNull properties. In fact, the only purpose of these methods is to change the returns value to the correctly typed *this.

class EditMinMaxNotNull : public EditValue<DataType, Cv> 

Similar to EditMinMax template class, but constructs activate NotNull property.

EditMinMaxNotNull& operator=(const DataType& t)

This helper operator allows direct assignment of value type to the editor.

Default constructor.

This constructor sets Min and Max properties.

EditMinMaxNotNull& Min(DataType min)

EditMinMaxNotNull& Max(DataType max)

EditMinMaxNotNull& NotNull(bool nn = true)

Sets Min, Max and NotNull properties. In fact, the only purpose of these methods is to change the returns value to the correctly typed *this.

Based on EditMinMax and EditMinMaxNotNull, basic value editors are defined as typedefs:

Some value editors are not based on EditMinMax and EditMinMaxNotNull:

class EditString : public EditValue<WString, ConvertString> 

EditString is not based on EditMinMax because instead of minimal and maximal values, it implements "maximum number of characters" constraint.

operator const WString&() const

This helper operator allows direct retrieval of value type from the editor.

EditString& operator=(const WString& data)

EditString& operator=(const String& data)

These helper operators allow a direct assignment of value type to the editor.

Default constructor.

This constructor sets maxlen as maximum length of contained text.

EditString& MaxLen(int maxlen)

Sets maxlen as maximum length of contained text.maxlen Returns *this.

EditString& NotNull(bool nn = true)

Sets NotNull property.

class EditStringNotNull : public EditString

This class sets the NotNull property in the constructors.

EditStringNotNull& operator=(const WString& data)

EditStringNotNull& operator=(const String& data)

These helper operators allow a direct assignment of value type to the editor.

Default constructor.

This constructor sets maxlen as maximum length of contained text.

class EditIntSpin : public EditInt

This editor adds spin buttons to the EditInt class.

EditIntSpin& ShowSpin(bool s = true)

Shows/hides spin buttons.

Default constructor. Spin buttons are on.

This constructor sets the  min max values. Spin buttons are on.

class EditDoubleSpin : public EditDouble

This editor adds spin buttons to the EditInt class.

EditDoubleSpin& SetInc(double inc = 0.1)

Set the spin increment.

Returns current spin increment.

EditDoubleSpin& ShowSpin(bool s = true)

Shows/hides spin buttons.

Sets the spin increment. Spin buttons are on.

This constructor sets min, max and inc values. Spin buttons are on.
