How to add a text label with every shape I draw using QPainter

BigBen

Hi.

I am drawing several shapes (rectangles, lines, ellipse...) on a label (QLabel) using QPainter. This is working fine.
However, now I want to add a title/label for each shape I draw after I am done drawing it. So, when I finish drawing a shape, a title (line 1, line 2, rectangle 1, etc. ) for that shape should appear anywhere near the body of that shape.

I am not able to understand how to achieve this.

@BigBen Are you drawing the labels in that same method, or are they drawn somewhere else? Can you show the relevant parts?

Hi.

I am not drawing the labels yet, as I have no idea how to achieve that.

The relevant code for drawing the shapes is as follows:
All this is in one function.

QPainterPath* ThePath = myShape->myQPainterPath();
myPen.setColor(myShape->color());
myPen.setWidth(myShape->thickness());
myPen.setStyle(myShape->style());
thisPainter.setPen(myPen);
thisPainter.drawPath(*ThePath);

Hi,

What is the goal of your application ?

Depending on that you can either draw the text at the same time as the path or maybe consider using the Graphics View Framework and use different items for the paths and the labels.

I'm using QPainter to draw various forms (rectangles, lines, ellipses, etc.) on a label (QLabel). Everything is going well.
Now I want to give each form I design a title or label after I finish sketching it. As a result, whenever I'm done sketching a form, its title (such as line 1, line 2, rectangle 1, etc.) ought to be visible somewhere close to the shape's body.

Is there a question hidden there ?

@Birdwell
Do you have a question on how to draw some text near the lines of your shapes or is that ok now?

@Birdwell
Next to where you call thisPainter.drawPath(*ThePath); to draw the shape call thisPainter.drawText(...) You will need to set the point or rectangle where you want the text based on the point/rectangle where you are drawing the shape. You will want to adjust from that one to be somewhere a bit outside it so that your text does not write onto the shape.
