My problems: There is a scrollView with many buttons (items). Above it there are 2 function buttons (return, start). <ol> <li>When I scroll down item buttons overlie function buttons. When I swallow all touches above my scrollview I will lose my function buttons. So I have to find another solution.</li> <li>When I start draging scroll view a item button is pressed. When I ended the button action will be execute. This is very annoying.</li> </ol> But there is the solution. I have created new CCControlButton. It checks whether was clicked outside scrollview or was dragged. The button is used for items buttons. <pre><code>bool ControlButtonForScrolling::checkIfTouchIsInsideScrollView(CCTouch *pTouch) { CCPoint touchLocation = pTouch->getLocation(); // Get the touch position touchLocation = _scrollView->getParent()->convertToNodeSpace(touchLocation); CCRect bBox=_scrollView->boundingBox(); bool result = bBox.containsPoint(touchLocation); return result; } bool ControlButtonForScrolling::ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent) { bool isInside = this->checkIfTouchIsInsideScrollView(pTouch); if (isInside) { return CCControlButton::ccTouchBegan(pTouch, pEvent); } else { return false; } } void ControlButtonForScrolling::ccTouchMoved(CCTouch *pTouch, CCEvent *pEvent) { CCControlButton::ccTouchMoved(pTouch, pEvent); _scrollWasDragged = true; // information about dragging is stored to prevent sending action } void ControlButtonForScrolling::ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent) { // this method is a copy of CCControlButton::ccTouchEnded except lines with _scrollWasDragged m_eState = CCControlStateNormal; m_isPushed = false; setHighlighted(false); if (!_scrollWasDragged) { if (isTouchInside(pTouch)) { sendActionsForControlEvents(CCControlEventTouchUpInside); } else { sendActionsForControlEvents(CCControlEventTouchUpOutside); } } _scrollWasDragged = false; } </code></pre>

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.
