Detailed Description

DsSelectionBase is a base class that contains a selection value.

Member Function Documentation

int32_t DsSelectionBase::getSelection ( void ) const

Returns the selection value.

void DsSelectionBase::setOnChangeCallback ( const lambda< void(int32_t selection, bool in_motion, bool user_input)> & cb )

Sets the lambda that will receive selection change events.

Parameters

action

Lambda of type void(int32_t state, bool user_input) that will be called whenever the selection changes.

selection is the new selection.
in_motion is true if the control is still in motion and false when the motion stopped and the user lifted the finger off the control.
user_input is true if the change happened as a result of the user touching the control or false if the state was changed programatically by calling the setSelection() method.

void DsSelectionBase::setSelection ( int32_t selection )

Sets the selection value.

Parameters

state New selection value. It will be saturated to the number of allowed selections. -1 means no selection is active.
