Detailed Description

Multiline edit widget for Kexi forms.

Constructor & Destructor Documentation

◆ KexiDBTextEdit()

KexiDBTextEdit::KexiDBTextEdit	(	TQWidget *	parent,
		const char *	name = 0 )

Definition at line 31 of file kexidbtextedit.cpp.

◆ ~KexiDBTextEdit()

KexiDBTextEdit::~KexiDBTextEdit ( )

virtual

Definition at line 42 of file kexidbtextedit.cpp.

Member Function Documentation

◆ clear()

void KexiDBTextEdit::clear ( )

virtual

clears item's data, so the data will contain NULL data

Implements KexiDataItemInterface.

Definition at line 131 of file kexidbtextedit.cpp.

◆ createPopupMenu()

TQPopupMenu * KexiDBTextEdit::createPopupMenu ( const TQPoint & pos )

protected

Definition at line 151 of file kexidbtextedit.cpp.

◆ cursorAtEnd()

bool KexiDBTextEdit::cursorAtEnd ( )

virtual

Returns: true if the item widget's cursor (whatever that means, eg. line edit cursor) is at the end of editor's contents. This can inform table/form view that after pressing "right arrow" key should stop editing and move to a field on the right hand.

Implements KexiDataItemInterface.

Definition at line 124 of file kexidbtextedit.cpp.

◆ cursorAtStart()

bool KexiDBTextEdit::cursorAtStart ( )

virtual

Returns: true if the item widget's cursor (whatever that means, eg. line edit cursor) is at the beginning of editor's contents. This can inform table/form view that after pressing "left arrow" key should stop editing and move to a field on the left hand.

Implements KexiDataItemInterface.

Definition at line 117 of file kexidbtextedit.cpp.

◆ dataSource()

TQString KexiDBTextEdit::dataSource ( ) const

inline

Definition at line 44 of file kexidbtextedit.h.

◆ dataSourceMimeType()

TQCString KexiDBTextEdit::dataSourceMimeType ( ) const

inline

Definition at line 45 of file kexidbtextedit.h.

◆ isReadOnly()

bool KexiDBTextEdit::isReadOnly ( ) const

virtual

Returns: 'readOnly' flag for this widget.

Reimplemented from KexiDataItemInterface.

Definition at line 91 of file kexidbtextedit.cpp.

◆ keyPressEvent()

void KexiDBTextEdit::keyPressEvent ( TQKeyEvent * ke )

virtual

Windows uses Ctrl+Tab for moving between tabs, so do not steal this shortcut.

Definition at line 199 of file kexidbtextedit.cpp.

◆ moveCursorToEnd

void KexiDBTextEdit::moveCursorToEnd ( )

virtualslot

Implemented for KexiDataItemInterface.

Definition at line 184 of file kexidbtextedit.cpp.

◆ moveCursorToStart

void KexiDBTextEdit::moveCursorToStart ( )

virtualslot

Implemented for KexiDataItemInterface.

Definition at line 189 of file kexidbtextedit.cpp.

◆ paintEvent()

void KexiDBTextEdit::paintEvent ( TQPaintEvent * pe )

protectedvirtual

Definition at line 144 of file kexidbtextedit.cpp.

◆ selectAll

void KexiDBTextEdit::selectAll ( )

virtualslot

Implemented for KexiDataItemInterface.

Definition at line 194 of file kexidbtextedit.cpp.

◆ setColumnInfo()

void KexiDBTextEdit::setColumnInfo ( KexiDB::QueryColumnInfo * cinfo )

virtual

Used internally to set database column information. Reimplement if you need to do additional actions, e.g. set data validator based on field type. Don't forget about calling superclass implementation.

Reimplemented from KexiFormDataItemInterface.

Definition at line 136 of file kexidbtextedit.cpp.

◆ setDataSource

void KexiDBTextEdit::setDataSource ( const TQString & ds )

inlineslot

Definition at line 81 of file kexidbtextedit.h.

◆ setDataSourceMimeType

void KexiDBTextEdit::setDataSourceMimeType ( const TQCString & ds )

inlineslot

Definition at line 82 of file kexidbtextedit.h.

◆ setDisplayDefaultValue()

void KexiDBTextEdit::setDisplayDefaultValue	(	TQWidget *	widget,
		bool	displayDefaultValue )

virtual

If displayDefaultValue is true, the value set by KexiDataItemInterface::setValue() is displayed in a special way. Used by KexiFormDataProvider::fillDataItems(). widget is equal to 'this'. Reimplemented after KexiFormDataItemInterface.

Todo: support rich text...

Reimplemented from KexiFormDataItemInterface.

Definition at line 163 of file kexidbtextedit.cpp.

◆ setInvalidState()

void KexiDBTextEdit::setInvalidState ( const TQString & displayText )

virtual

Sets 'invalid' state, e.g. a text editor widget should display text displayText and become read only to prevent entering data, because updating at the database backend is not available. displayText is usually set to something i18n'd like "#NAME?". Note: that even widgets that usualy do not display texts (e.g. pixmaps) should display displayText too.

Todo: move this to KexiDataItemInterface::setInvalidStateInternal() ?

Implements KexiFormDataItemInterface.

Definition at line 46 of file kexidbtextedit.cpp.

◆ setReadOnly

void KexiDBTextEdit::setReadOnly ( bool readOnly )

virtualslot

Definition at line 96 of file kexidbtextedit.cpp.

◆ setText

void KexiDBTextEdit::setText	(	const TQString &	text,
		const TQString &	context )

virtualslot

Definition at line 107 of file kexidbtextedit.cpp.

◆ setValueInternal()

void KexiDBTextEdit::setValueInternal	(	const TQVariant &	add,
		bool	removeOld )

protectedvirtual

Initializes this editor with add value, which should be somewhat added to the current value (already storted in m_origValue). If removeOld is true, a value should be set to add, otherwise -it should be set to current m_origValue + add, if possible. Implement this.

Todo: temporary solution for booleans!

Implements KexiDataItemInterface.

Definition at line 55 of file kexidbtextedit.cpp.

◆ slotTextChanged

void KexiDBTextEdit::slotTextChanged ( )

protectedslot

Definition at line 74 of file kexidbtextedit.cpp.

◆ undo

void KexiDBTextEdit::undo ( )

virtualslot

Reimplemented, so "undo" means the same as "cancelEditor" action

Todo: enable "real" undo internally so user can use ctrl+z while editing

Definition at line 158 of file kexidbtextedit.cpp.

◆ value()

TQVariant KexiDBTextEdit::value ( )

virtual

Returns: value currently represented by this item.

Implements KexiDataItemInterface.

Definition at line 69 of file kexidbtextedit.cpp.

◆ valueIsEmpty()

bool KexiDBTextEdit::valueIsEmpty ( )

virtual

Returns: true if editor's value is empty (not necessary null). Only few data types can accept "EMPTY" property (use KexiDB::Field::hasEmptyProperty() to check this). Used for checking if a given constraint within table or form is met.

Implements KexiDataItemInterface.

Definition at line 86 of file kexidbtextedit.cpp.

◆ valueIsNull()

bool KexiDBTextEdit::valueIsNull ( )

virtual

Returns: true if editor's value is null (not empty) Used for checking if a given constraint within table of form is met.

Implements KexiDataItemInterface.

Definition at line 81 of file kexidbtextedit.cpp.

◆ widget()

TQWidget * KexiDBTextEdit::widget ( )

virtual

Returns: the view widget of this item, e.g. line edit widget.

Reimplemented from KexiFormDataItemInterface.

Definition at line 112 of file kexidbtextedit.cpp.

Member Data Documentation

◆ m_menuExtender

KexiDBWidgetContextMenuExtender KexiDBTextEdit::m_menuExtender

protected

Used for extending context menu.

Definition at line 108 of file kexidbtextedit.h.

◆ m_slotTextChanged_enabled

bool KexiDBTextEdit::m_slotTextChanged_enabled

protected

Used to disable slotTextChanged().
