The relationship between widgets** 266 266 218 +There are two common relationships between 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. 267 267 268 -Widgets commonly have two types of relationships: **parallel** and **parent-child**. 269 - 270 -* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object. 271 -* 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. 272 - 273 273 [[image:1727486567182-334.png||height="318" width="278"]] 274 274 222 +image 12 move label1 to make label1 widget be a child of button1 widget(1) 275 275 276 -Move the label, **Label1** to make it a child of **Button1** as shown in the image below. 277 - 278 278 [[image:image-20240928112001-8.png||height="431" width="796"]] 279 279 226 + image 13 move label1 to make label1 widget be a child of button1 widget(2) 280 280 281 - Then set the**X** and **Y** position of the label to **0** as shown in the image below.The label will appearon thebutton.
