Graphics View

[parulkalra14]

This code is to match a text int in a block and draw a rectangle at a given position. That is working correctly for one variable but i want when two variables are there in a program then two rectangles will draw.
For Example :
int a,b;
then i want two rectangles will appear (one rectangle for variable a and another for variable b) in graphics view
Can someone help me?

if(cursor.block().text().contains("int",Qt::CaseInsensitive))
{
scene.addRect(100,0,90,90,QPen(Qt::black),QBrush(Q t::darkBlue));
ui->graphicsView->setScene(&scene);

}

If you want one rectangle, you call addRect() onces.
If you want two rectangles, you call addRect() twice. With different coordinates or size if you want them to visually distinguishable.

Sir for one program this solution is fine but not for bulk of programs. I want if one variable then one rectangle will show, if two variables then two rectangles will show , if three variables three rectangles will show and so on.

Then draw your rectangles in a loop...

You will be surprised to read this, but in order to get three rectangles, addRect() needs to be called three times!

If we assume the laws of induction apply, we can derive that in order to get N rectangles, you'll need to call addRect() N times.
