Detailed Description

Basic implementation of selection parameter.

Definition at line 22 of file CSelectionParam.h.

Constructor & Destructor Documentation

◆ CSelectionParam()

iprm::CSelectionParam::CSelectionParam ( )

Member Function Documentation

◆ CalcIndexFromId()

int iprm::CSelectionParam::CalcIndexFromId ( const QByteArray &  optionId,
int  suggestedIndex = NO_SELECTION 
) const
protected

Calculate optimal index based on current selected index and ID.

◆ CloneMe()

virtual istd::TUniqueInterfacePtr< istd::IChangeable > iprm::CSelectionParam::CloneMe ( CompatibilityMode  mode = CM_WITHOUT_REFS) const
overridevirtual

Make a copy of this object.

Returns
new instance or NULL, if this operation is not supported.

Reimplemented from istd::IChangeable.

◆ CopyFrom()

virtual bool iprm::CSelectionParam::CopyFrom ( const istd::IChangeable object,
CompatibilityMode  mode = CM_WITHOUT_REFS 
)
overridevirtual

Copy this object from another one.

Default implementation in istd::IChangeable does nothing.

Reimplemented from istd::IChangeable.

Reimplemented in iser::TCopySerializedWrap< iprm::CSelectionParam >.

◆ GetActiveSubselection()

ISelectionParam * iprm::CSelectionParam::GetActiveSubselection ( ) const

Get sub-selection for the currently selected option.

◆ GetOptionIndexById()

int iprm::CSelectionParam::GetOptionIndexById ( const QByteArray &  optionId) const

Get index of an option by ID.

◆ GetSelectedOptionIndex()

virtual int iprm::CSelectionParam::GetSelectedOptionIndex ( ) const
overridevirtual

Get selected index.

Returns the index of the currently selected option.

Returns
Index of selected option (0-based), or NO_SELECTION (-1) if no option is selected.
int index = selection.GetSelectedOptionIndex();
{
qDebug() << "No selection";
}
else
{
qDebug() << "Selected index:" << index;
}
@ NO_SELECTION
Indicates no option is currently selected.

SetSelectedOptionIndex, NO_SELECTION

Implements iprm::ISelectionParam.

◆ GetSelectionConstraints()

virtual const IOptionsList * iprm::CSelectionParam::GetSelectionConstraints ( ) const
overridevirtual

Get constraints of this parameter.

Returns the options list that defines available choices for this selection. Constraints describe allowed parameter ranges and related information.

Returns
Pointer to IOptionsList defining available options, owned by the parameter or external manager. Do not delete.
const iprm::IOptionsList* options = selection.GetSelectionConstraints();
if (options)
{
int count = options->GetOptionsCount();
for (int i = 0; i < count; ++i)
{
QString name = options->GetOptionName(i);
qDebug() << "Option" << i << ":" << name;
}
}
Constraints of selection from set of possibilities.
virtual int GetOptionsCount() const =0
Get number of managed options.
virtual QString GetOptionName(int index) const =0
Get name of specified option.
See also
IOptionsList

Implements iprm::ISelectionParam.

◆ GetSubselection()

virtual ISelectionParam * iprm::CSelectionParam::GetSubselection ( int  index) const
overridevirtual

Get sub-selection for specified option.

Retrieves the hierarchical sub-selection associated with a specific option. This enables multi-level selection structures (e.g., Category -> Subcategory).

Parameters
indexIndex of the option whose sub-selection to retrieve.
Returns
Pointer to sub-selection parameter, or NULL if no sub-selection exists for this option.
Note
The returned pointer belongs to the selection's data model. Do not delete.
Sub-selections are independent selection parameters that can have their own constraints and further sub-selections.
// Get sub-selection for currently selected option
int selectedIndex = selection.GetSelectedOptionIndex();
if (selectedIndex >= 0)
{
iprm::ISelectionParam* subSelection = selection.GetSubselection(selectedIndex);
if (subSelection)
{
// Work with sub-selection
subSelection->SetSelectedOptionIndex(0);
}
}
// Check all options for sub-selections
const iprm::IOptionsList* options = selection.GetSelectionConstraints();
int count = options->GetOptionsCount();
for (int i = 0; i < count; ++i)
{
if (sub)
{
qDebug() << "Option" << i << "has a sub-selection";
}
}
Interface allowing to select single option from list of options.
virtual bool SetSelectedOptionIndex(int index)=0
Set index of selected option.
virtual ISelectionParam * GetSubselection(int index) const =0
Get sub-selection for specified option.

Implements iprm::ISelectionParam.

Reimplemented in iprm::CSelectionParamComp.

◆ Serialize()

virtual bool iprm::CSelectionParam::Serialize ( iser::IArchive archive)
overridevirtual

Load or store state of this object as a archive stream.

Type of operation is depending on archive type.

See also
iser::IArchive

Implements iser::ISerializable.

Reimplemented in iprm::COptionsManager.

◆ SetSelectedOptionById()

bool iprm::CSelectionParam::SetSelectedOptionById ( const QByteArray &  selectedOptionId)

Set selection index according to a given option ID.

◆ SetSelectedOptionIndex()

virtual bool iprm::CSelectionParam::SetSelectedOptionIndex ( int  index)
overridevirtual

Set index of selected option.

Changes the selected option to the specified index.

Parameters
indexIndex of the option to select (0-based), or NO_SELECTION to clear the selection.
Returns
true if selection change was possible and successful, false otherwise.
Note
Returns false if index is out of range or the option is disabled.
Triggers CF_SELECTION_CHANGED notification on success.
// Select third option
bool success = selection.SetSelectedOptionIndex(2);
if (success)
{
qDebug() << "Selection changed";
}
// Clear selection
selection.SetSelectedOptionIndex(iprm::ISelectionParam::NO_SELECTION);
See also
GetSelectedOptionIndex, CF_SELECTION_CHANGED

Implements iprm::ISelectionParam.

◆ SetSelectionConstraints()

void iprm::CSelectionParam::SetSelectionConstraints ( const IOptionsList constraintsPtr)

Set selection constraints for this selection object.

◆ SetSubselection()

void iprm::CSelectionParam::SetSubselection ( int  selectionIndex,
ISelectionParam selectionPtr 
)

Set sub-selection for a given option index.

◆ SyncIndexWithId()

bool iprm::CSelectionParam::SyncIndexWithId ( )
protected

Synchronize current index to optimal one.
