The relationship between widgets** 213 213 214 -The rearetwo common relationshipsbetween widgets:one is parallel, the other is parent-child. The parallel relationship means that widgets' relative position is based on a collective object of reference. In parent-child relationship, the parts of the child object that are outside the boundaries of the parent object are not visible by default. Therefore, we need to adjust the position of the child object so that it falls within the range of the parent object, allowing it to be seen as illustrated in image 13.269 +==== **The relationship between widgets** ==== 215 215 271 + 272 +Widgets commonly have two types of relationships: **parallel** and **parent-child**. 273 + 274 +* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object. 275 +* In a **parent-child relationship**, any part of the child object outside the parent's boundaries is hidden by default.
