The relationship between widgets** 264 264 212 +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. 265 265 266 -Widgets commonly have two types of relationships: **parallel** and **parent-child**. 267 - 268 -* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object. 269 -* 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. 270 - 271 271 [[image:1727486567182-334.png||height="318" width="278"]] 272 272 216 +image 12 move label1 to make label1 widget be a child of button1 widget(1) 273 273 274 -Move the label, **Label1** to make it a child of **Button1** as shown in the image below. 275 - 276 276 [[image:image-20240928112001-8.png||height="431" width="796"]] 277 277 220 + image 13 move label1 to make label1 widget be a child of button1 widget(2) 278 278 279 - Then set the**X** and **Y** position of the label to **0** as shown in the image below.The label will appearon thebutton.
