示例1: testFindingTables
void testFindingTables()
{
// How to find all the tables in a QTextDocument?
QTextDocument textDoc;
QTextCursor c( &textDoc );
QTextTable* firstTable = c.insertTable( 2, 2 );
QTextTableCell bottomRight = firstTable->cellAt( 1, 1 );
QTextTable* secondTable = bottomRight.firstCursorPosition().insertTable( 3, 3 ); // a nested table
c.movePosition( QTextCursor::End );
QTextTable* thirdTable = c.insertTable( 1, 1 );
thirdTable->firstCursorPosition().insertText( "in table" );
c.insertText( "Foo" );
QList<QTextTable *> origTables;
origTables << firstTable << secondTable << thirdTable;
// A generic and slow solution is
// curs.currentTable() && !tablesFound.contains(curs.currentTable())
// for each cursor position. Surely there's better.
// We could jump to currentFrame().lastCursorPosition() but then it would skip
// nested tables.
QTextDocument* clonedDoc = textDoc.clone();
QSet<QTextTable *> tablesFound;
{
QTextCursor curs(clonedDoc);
while (!curs.atEnd()) {
QTextTable* currentTable = curs.currentTable();
if ( currentTable && !tablesFound.contains(currentTable) ) {
tablesFound.insert( currentTable );
}
curs.movePosition( QTextCursor::NextCharacter );
}
QCOMPARE( tablesFound.size(), 3 );
}
// Let's do something else then, let's find them by cursor position
QList<QTextTable *> tablesByPos;
{
// first test
const int firstPos = firstTable->firstCursorPosition().position();
QTextCursor curs( clonedDoc );
curs.setPosition( firstPos );
QVERIFY( curs.currentTable() );
// generic loop. works this approach is in TextDocument::breakTables now.
