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. 266 266 267 -Widgets commonly have two types of relationships: **parallel** and **parent-child**. 268 - 269 -* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object. 270 -* In a **parent-child relationship**, any part of the child object outside the parent's boundaries is hidden by default. To make the child object fully visible, you must adjust its position to fit within the parent's range. 271 - 272 272 [[image:1727486567182-334.png||height="318" width="278"]] 273 273 198 +image 12 move label1 to make label1 widget be a child of button1 widget(1) 274 274 275 -Move the label, **Label1** to make it a child of **Button1** as shown in the image below. 276 - 277 277 [[image:image-20240928112001-8.png||height="431" width="796"]] 278 278 202 + image 13 move label1 to make label1 widget be a child of button1 widget(2) 279 279 280 - Then set the**X** and **Y** position of the label to **0** as shown in the image below.The label will appearon thebutton.
