problem with tablewidget..

[reshma]

hello,

my problem is that i need to remove all the rows of the table and then add new rows..
al these work at runtime only..

so i wrote the following code...
but cant understand where the problem is..

row=table->rowCount();
for(int i=0;i<=row;i++)
table->removeRow(i);
row=0;
queryForMem();//this takes input for the new row..

one row always remains and doesnt get removed..
new instructions do not work on this table any more...

like i cannot add a new row through some other functions..

plz help me out...

why do not simply call QTableWidget::clear?
PS. please, use tags CODE .

Damn, you are very resistant to advices! USE THE FUCKING CODE TAGS! The last time I'll help you when you are not going to use them:
QTableWidget::clearContents(), and then reset the dimension.

do u mean like dis...

row=table->rowCount();
for(int i=0;i<=row;i++)
table->removeRow(i);
row=0;
queryForMem();//this takes input for the new row..

row=table->rowCount();
for(int i=0;i<=row;i++)
table->removeRow(i);
row=0;
queryForMem();//this takes input for the new row..

To copy to clipboard, switch view to plain text mode 

ok.. but clear() doent remove the rows totally...it just removes the contents..

set row count to "0" after clear.
