    <p>Here is the draw function which draws the parts of the car, in this function car rims is checked and flag is checked, and i need to rotate the tire rim as i move the car. Something is not working since the rims are rotated but taken out from the car model, when i press up arrow key, but the car does move.</p> <p>I also initialized self.fFlag = "false" in initialize function:</p> <pre><code>def on_draw(self): # Clears the screen and draws the car # If needed, extra transformations may be set-up here glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) for name in self.parts: colors = self.colors color = colors.get(name, colors["default"]) glColor3f(*color) if (name == 'Front Driver tire rim') &amp; (self.fFlag == "true"): bodyFace = self.mini.group(name) glPushMatrix() glRotatef(45,1,0,0) # Drawing the rim for face in bodyFace: if len(face) == 3: glBegin(GL_TRIANGLES) elif len(face) == 4: glBegin(GL_QUADS) else: glBegin(GL_POLYGON) for i in face: glNormal3f(*self.mini.normal(i)) glVertex3f(*self.mini.vertex(i)) glEnd() glPopMatrix() self.fFlag == "false" else: bodyFace = self.mini.group(name) for face in bodyFace: if len(face) == 3: glBegin(GL_TRIANGLES) elif len(face) == 4: glBegin(GL_QUADS) else: glBegin(GL_POLYGON) for i in face: glNormal3f(*self.mini.normal(i)) glVertex3f(*self.mini.vertex(i)) glEnd() def on_key_release(self, symbol, modifiers): """Process a key pressed event. """ if symbol == key.UP: # Move car forward # TODO glTranslatef(0,-1,0) self.fFlag = "true" self.on_draw() pass </code></pre> <p>Edited: I am trying to make the car rims to rotate when i press the up arrow key, which moves the car forward.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
