Detailed Description

A text table item that reads text from string lists.

Constructor & Destructor Documentation

QgsLayoutItemTextTable()

QgsLayoutItemTextTable::QgsLayoutItemTextTable

(

QgsLayout *

layout

)

Constructor for QgsLayoutItemTextTable, for the specified layout.

Ownership is transferred to the layout.

Definition at line 23 of file qgslayoutitemtexttable.cpp.

Member Function Documentation

addRow()

void QgsLayoutItemTextTable::addRow

(

const QStringList &

row

)

Adds a row to the table.

Parameters

row	list of strings to use for each cell's value in the newly added row

Note

If row is shorter than the number of columns in the table than blank cells will be inserted at the end of the row. If row contains more strings then the number of columns in the table then these extra strings will be ignored.

if adding many rows, setContents() is much faster

Definition at line 44 of file qgslayoutitemtexttable.cpp.

create()

QgsLayoutItemTextTable * QgsLayoutItemTextTable::create ( QgsLayout *  layout )

static

Returns a new QgsLayoutItemTextTable for the specified parent layout.

Definition at line 39 of file qgslayoutitemtexttable.cpp.

displayName()

QString QgsLayoutItemTextTable::displayName ( ) const

overridevirtual

Returns the multiframe display name.

Reimplemented from QgsLayoutMultiFrame.

Definition at line 34 of file qgslayoutitemtexttable.cpp.

getTableContents()

bool QgsLayoutItemTextTable::getTableContents ( QgsLayoutTableContents &  contents )

overridevirtual

Fetches the contents used for the cells in the table.

Returns

true if table contents were successfully retrieved.

Parameters

contents

QgsLayoutTableContents to store retrieved row data in

Implements QgsLayoutTable.

Definition at line 56 of file qgslayoutitemtexttable.cpp.

setContents()

void QgsLayoutItemTextTable::setContents

(

const QVector< QStringList > &

contents

)

Sets the contents of the text table.

Parameters

contents

list of table rows

type()

int QgsLayoutItemTextTable::type ( ) const

overridevirtual

Returns unique multiframe type id.
