Constructor & Destructor Documentation

◆ KexiTableViewColumn() [1/5]

KexiTableViewColumn::KexiTableViewColumn ( KexiDB::Field & f,
bool owner = false )

Not db-aware ctor. if owner is true, the field will be owned by this column, so you shouldn't care about destroying this field.

Definition at line 46 of file kexitableviewdata.cpp.

◆ KexiTableViewColumn() [2/5]

KexiTableViewColumn::KexiTableViewColumn ( const TQString & name,
KexiDB::Field::Type ctype,
uint cconst = KexiDB::Field::NoConstraints,
uint options = KexiDB::Field::NoOptions,
uint length = 0,
uint precision = 0,
TQVariant defaultValue = TQVariant(),
const TQString & caption = TQString(),
const TQString & description = TQString(),
uint width = 0 )

Not db-aware, convenience ctor, like above. The field is created using specified parameters that are equal to these accepted by KexiDB::Field ctor. The column will be the owner of this automatically generated field.

Definition at line 57 of file kexitableviewdata.cpp.

◆ KexiTableViewColumn() [3/5]

KexiTableViewColumn::KexiTableViewColumn ( const TQString & name,
KexiDB::Field::Type ctype,
const TQString & caption,
const TQString & description = TQString() )

Not db-aware, convenience ctor, simplified version of the above.

Definition at line 81 of file kexitableviewdata.cpp.

◆ KexiTableViewColumn() [4/5]

KexiTableViewColumn::KexiTableViewColumn ( const KexiDB::QuerySchema & query,
KexiDB::QueryColumnInfo & aColumnInfo,
KexiDB::QueryColumnInfo * aVisibleLookupColumnInfo = 0 )

Db-aware version.

Todo
2.0: remove this when queries become editable ^^^^^^^^^^^^^^

Definition at line 208 of file kexitableviewdata.cpp.

◆ captionAliasOrName()

TQString KexiTableViewColumn::captionAliasOrName ( ) const

Returns
whatever is available:
  • field's caption
  • or field's alias (from query)
  • or finally - field's name

Definition at line 123 of file kexitableviewdata.h.

◆ field()

KexiDB::Field * KexiTableViewColumn::field ( ) const
inline
Returns
field for this column. For db-aware information is taken from columnInfo member.

Definition at line 149 of file kexitableviewdata.h.

◆ icon()

TQIconSet KexiTableViewColumn::icon ( ) const

Returns
bame of icon displayed in the caption area (header).

Definition at line 109 of file kexitableviewdata.h.

◆ init()

protected

Definition at line 157 of file kexitableviewdata.cpp.

◆ isHeaderTextVisible()

bool KexiTableViewColumn::isHeaderTextVisible ( ) const
inline
Returns
true if caption has to be displayed in the column's header, (or field's name if caption is empty.

Definition at line 117 of file kexitableviewdata.h.

◆ isReadOnly()

bool KexiTableViewColumn::isReadOnly ( ) const
Returns
true if the column is read-only For db-aware column this can depend on whether the column is in parent table of this query.
See also
setReadOnly()

Definition at line 203 of file kexitableviewdata.cpp.

◆ relatedData()

KexiTableViewData * KexiTableViewColumn::relatedData ( ) const
inline

For not-db-aware data only: Related data data for this column, what defines simple one-field. NULL by default.

See also
setRelatedData()

Definition at line 145 of file kexitableviewdata.h.

◆ relatedDataEditable()

bool KexiTableViewColumn::relatedDataEditable ( ) const
inline

Only usable if related data is set (ie. this is for combo boxes).

Returns
'editable' flag for this column. False by default.
See also
setRelatedDataEditable(bool).

Definition at line 159 of file kexitableviewdata.h.

◆ setHeaderTextVisible()

void KexiTableViewColumn::setHeaderTextVisible ( bool visible)
inline

If visible is true, caption has to be displayed in the column's header, (or field's name if caption is empty. True by default.

Definition at line 113 of file kexitableviewdata.h.

◆ setIcon()

void KexiTableViewColumn::setIcon ( const TQIconSet & icon)
inline

Sets icon for displaying in the caption area (header).

Definition at line 106 of file kexitableviewdata.h.

◆ setReadOnly()

void KexiTableViewColumn::setReadOnly ( bool ro)
inline

forces readOnly flag to be set to ro

Definition at line 93 of file kexitableviewdata.h.

◆ setRelatedData()

void KexiTableViewColumn::setRelatedData ( KexiTableViewData * data)

For not-db-aware data only: Sets related data data for this column, what defines simple one-field, one-to-many relationship between this column and the primary key in data. The relationship will be used to generate a popup editor instead of just regular editor. This assignment has no result if data has no primary key defined. data is owned, so is will be destroyed when needed. It is also destroyed when another data (or NULL) is set for the same column.

Definition at line 177 of file kexitableviewdata.cpp.

◆ setRelatedDataEditable()

void KexiTableViewColumn::setRelatedDataEditable ( bool set)

Only usable if related data is set (ie. this is for combo boxes). Sets 'editable' flag for this column, what means a new value can be entered by hand. This is similar to TQComboBox::setEditable().

Definition at line 198 of file kexitableviewdata.cpp.

◆ setValidator()

void KexiTableViewColumn::setValidator ( KexiUtils::Validator * v)

Assigns validator v for this column. If the validator has no parent object, it will be owned by the column, so you shouldn't care about destroying it.

Definition at line 168 of file kexitableviewdata.cpp.

◆ setVisible()

void KexiTableViewColumn::setVisible ( bool v)
inline

Changes column visibility.

Definition at line 99 of file kexitableviewdata.h.

◆ validator()

KexiUtils::Validator * KexiTableViewColumn::validator ( ) const
inline
Returns
validator assigned for this column of 0 if there is no validator assigned.

Definition at line 131 of file kexitableviewdata.h.

◆ visible()

bool KexiTableViewColumn::visible ( ) const
inline

Column visibility. By default column is visible.
