Detailed Description

The ParameterWidget provides a consistent user and programming interface for managing query criteria.

The ParameterWidget can be used to set filtering criteria to apply to MetaSQL queries. The application developer defines what criteria can be used (e.g. filter by a date range), what the default values should be, if any, and which criteria are mandatory. The user then chooses which criteria to actually use at runtime and supplies values (e.g. 'January 1, 2010' through 'December 31, 2010').

It is the application developer's responsibility to ensure that the user's selections are honored by the query.

Specific sets of filtering criteria can be saved, reused, and shared between users. The details of the filter can be hidden from view or made visible, allowing for efficient use of screen real estate.

If application preferences are available, the most recently selected filter will saved when the parent window closes and will be reselected when the window is next opened.

ParameterWidget()

ParameterWidget::ParameterWidget	(	QWidget *	pParent,
		const char *	pName = 0

~ParameterWidget()

ParameterWidget::~ParameterWidget

(

)

Member Function Documentation

addParam

void ParameterWidget::addParam ( )

slot

append

void ParameterWidget::append ( QString  pName, QString  pParam, enum ParameterWidgetTypes  pType = Text, QVariant  pDefault = QVariant(), bool  pRequired = false, QString  pExtraInfo = QString()  )

slot

Add a new filter to the set of available filters.

Parameters

pName	The user-visible name for this filter to distinguish it from other filters in the same set
pParam	The name to use for the parameter in the ParameterList
pType	The type of widget for the user to enter a criterion in
pDefault	The default value to use for this parameter
pRequired	Required parameters cannot be removed from the filter set
pExtraInfo	A query string to use if pType indicates a combo box or multiselect

appendComboBox [1/2]

void ParameterWidget::appendComboBox ( QString  pName, QString  pParam, int  pType, QVariant  pDefault = QVariant(), bool  pRequired = false  )

slot

Add a new XComboBox-based filter to the set of available filters.

Parameters

pName	The user-visible name for this filter to distinguish it from other filters in the same set
pParam	The name to use for the parameter in the ParameterList
pType	Set the XComboBox to use the corresponding XComboBox::XComboBoxTypes value
pDefault	The default internal id to select for this XComboBox
pRequired	Required parameters cannot be removed from the filter set

appendComboBox [2/2]

void ParameterWidget::appendComboBox ( QString  pName, QString  pParam, QString  pQuery, QVariant  pDefault = QVariant(), bool  pRequired = false  )

slot

Add a new XComboBox-based filter to the set of available filters.

Parameters

pName	The user-visible name for this filter to distinguish it from other filters in the same set
pParam	The name to use for the parameter in the ParameterList
pQuery	Set the XComboBox to populate itself with this query
pDefault	The default internal id to select for this XComboBox
pRequired	Required parameters cannot be removed from the filter set

appendValue()

void ParameterWidget::appendValue

(

ParameterList &

pParams

)

Add name/value pairs to the input ParameterList to reflect the current user selections.

The ParameterList passed in to this method is modified to reflect the current selections. Parameters already in the list have their associated values changed and parameters not in the list are added. No name/value pairs are removed from the list.

This should be used carefully, as cached ParameterLists may have name/value pairs that the caller does not expect.

Parameters

[in,out]

pParams

The ParameterList to modify

applyDefaultFilterSet()

void ParameterWidget::applyDefaultFilterSet

(

)

Find the default filter set for the ParameterWidget with the current parent and apply it.

This method searches for the default filter set based on the QObject::objectName of the parent and the QObject::objectName of this ParameterWidget instance. If it is found, then this filter set is applied.

applySaved

void ParameterWidget::applySaved ( int  pId = 0, int  filter_id = 0  )

slot

changeFilterObject

void ParameterWidget::changeFilterObject ( int  index )

slot

cleared

void ParameterWidget::cleared ( )

signal

clearFilters

void ParameterWidget::clearFilters ( )

slot

containsUsedType()

bool ParameterWidget::containsUsedType ( QString  value )

protected

filter()

QString ParameterWidget::filter

(

)

Returns a text based list separated by line feeds of parameter names and selected values. Can be useful when passed to printed reports as a header description of what filter has been applied to the presented data.

filterChanged

void ParameterWidget::filterChanged ( )

signal

filterSetSaved

void ParameterWidget::filterSetSaved ( )

signal

getFilterIndex()

int ParameterWidget::getFilterIndex ( const QWidget *  filterwidget )

protected

getFilterWidget()

QWidget * ParameterWidget::getFilterWidget ( const int  index )

protected

getParameterTypeKey()

QString ParameterWidget::getParameterTypeKey ( QString  pValue )

protected

parameters()

ParameterList ParameterWidget::parameters

)

paramIndex()

int ParameterWidget::paramIndex

(

QString

pName

)

Returns the index of an appended parameter definition of pName.

preferencePrefix()

QString ParameterWidget::preferencePrefix ( ) const

protectedvirtual

removeParam

void ParameterWidget::removeParam ( int  pRow )

slot

resetMultiselect

void ParameterWidget::resetMultiselect ( QTableWidgetItem *  item )

protectedslot

retranslateUi() [1/2]

void Ui_ParameterWidget::retranslateUi ( QWidget *  ParameterWidget )

inlineinherited

retranslateUi() [2/2]

void Ui_ParameterWidget::retranslateUi ( QWidget *  ParameterWidget )

inlineinherited

save

void ParameterWidget::save ( )

slot

setDefault

void ParameterWidget::setDefault ( QString  pName, QVariant  pDefault = QVariant(), bool  pAutoApply = false  )

slot

Set the default value on an existing parameter pName to pDefault. If pDefault is not passed or 0 then the previous default, if any, will be removed. if pAutoApply is true, then the default filter set will be automatically applied.

applyDefaultFilterSet();

setEnabled

void ParameterWidget::setEnabled ( QString  pName, bool  pEnabled  )

slot

Enable or disable an existing parameter pName to pEnabled. Useful if you want a specific value to be forced based on privilege control or some other specific criteria that would limit the user's selection ability. Is effective the next time a user instantiates the parameter.

setFiltersDefault

void ParameterWidget::setFiltersDefault ( )

slot

Sets the current filter as the default for the parent object it resides in.

setFiltersVisabiltyPreference

void ParameterWidget::setFiltersVisabiltyPreference ( )

slot

setFiltersVisible

void ParameterWidget::setFiltersVisible ( bool  visible )

slot

setSavedFilters

void ParameterWidget::setSavedFilters ( int  defaultId = -1 )

slot

Sets a saved filter set with Id defaultId to the currently selected filter. If no pDefaultId is provided the default filter will be used.

setSavedFiltersIndex(QString);

setSavedFiltersIndex

void ParameterWidget::setSavedFiltersIndex ( QString  filterSetName )
