[solved] Nested List support in QTextEdit

[pranap]

Hi, I'm trying to create the nested list using QTextEdit.

I tried with the below code snippet, but I'm getting the same number for all the blocks.
@QTextListFormat listFormat;
listFormat.setIndent(indent);
listFormat.setStyle(QTextListFormat::ListDecimal);

    const vector<int> cursorPositions = iter->getPositions();
    vector<int>::const_iterator posIter = cursorPositions .begin();
    vector<int>::const_iterator posIterEnd = cursorPositions .end();
    cursor.beginEditBlock();
    for(; posIter!= posIterEnd; posIter++)
    {
        cursor.setPosition(*posIter);
        cursor.insertList(listFormat);
     }
    cursor.endEditBlock()@

What is wrong in the above code snippet?

I already came across the below post which is about 2 years old.

Can someone provide me the input?

Hi and welcome to devnet,

Please enclose your code with coding tags (one @ at the beginning and one at the end) it will make it readable.

I would also suggest to give a more complete example (so others may test it) and explaining what you are expecting and what you get

Hi SGaist, thanks for your reply.

I want to represent the nested list items like in the below example.
@

1. first item
2. second Item
   1. first nested item
   2. second nested item
3. third item
   @

I actually achieved it by using the below code snippet.
@int indentArray[2] = {1,2};
int positions[2][];
//just for example, may not compile
//calculated cursor positions for the above mentioned examples
positions[0] = {0, 11, 60};
positions[1] = {23, 41};
for(int i=0; i< 2; i++)
{
int indent = indentArray[i];
QTextListFormat listFormat;
listFormat.setIndent(indent);
listFormat.setStyle(QTextListFormat::ListDecimal);
QTextList * list = NULL;
{
bool isListFormatApplied = false;
cursor.beginEditBlock();
int size = positions[i].getSize(); //for example
for(int j=0; j < sizs; j++)
{
cursor.setPosition(positions[i][j]);
if(isListFormatApplied == false)
{
list = cursor.createList(listFormat);
isListFormatApplied = true;
}
else
{
QTextBlock block = cursor.block();
if(list)
{
list->add(block);
}
}
}
cursor.endEditBlock();
}
}@

Please let me know if this is fine or if there is any other better way of getting this done.

Since you know your various list you could do something like

@
QTextEdit edit;
QTextCursor cursor(edit.document());
QTextListFormat listFormat;

listFormat.setStyle(QTextListFormat::ListDecimal);
listFormat.setNumberPrefix("(");
listFormat.setNumberSuffix(")");

cursor.insertList(listFormat);
cursor.insertText("test1\n");
cursor.insertText("test2\n");
cursor.insertText("test3\n");
cursor.insertText("test4");
cursor = edit.document()->find("test2");
cursor.movePosition(QTextCursor::EndOfLine);
listFormat.setIndent(2);
cursor.insertList(listFormat);
cursor.insertText("indent test1\n");
cursor.insertText("indent test2");

edit.show();

@

Hope it helps
