Tested with Qt 4.7.4 and 4.8-git
Description
for the following example:
#include <QApplication>
#include <QTextDocument>
#include <QTextCursor>
#include <QTextBlock>
#include <QDebug>
void dump_doc(QTextDocument *document)
{
QTextBlock b(document->firstBlock());
while (b.isValid())
{
qDebug() /*<< "position" << b.position()*/
/*<< "length" << b.length()*/
<< "blockNumber" << b.blockNumber()
<< "userState" << b.userState()
<< "text" << b.text()
;
b = b.next();
};
}
int main(int argc, char **argv)
{
QApplication app(argc, argv);
QTextDocument doc;
QTextBlock lastBlock;
{
QTextCursor cur(&doc);
cur.insertBlock();
cur.insertText("Hello");
cur.insertBlock();
cur.insertText("World!");
cur.block().setUserState(1);
lastBlock = cur.block();
}
dump_doc(&doc);
qDebug();
{
QTextCursor cur(lastBlock);
cur.select(QTextCursor::BlockUnderCursor);
cur.removeSelectedText();
}
dump_doc(&doc);
return 0;
}
the output is:
blockNumber 0 userState -1 text "" blockNumber 1 userState -1 text "Hello" blockNumber 2 userState 1 text "World!" blockNumber 0 userState -1 text "" blockNumber 1 userState 1 text "Hello"
First it has 3 Textblock and only the last "World!"-block has the userState 1, everything correct.
But now if we delete the last userState Block, the "Hello"-block suddenly gets the userState 1, which is wrong, it should still be -1.
So in short, the expected output should be
blockNumber 0 userState -1 text ""
blockNumber 1 userState -1 text "Hello"
