This article introduces various operations of the QGridLayout control in detail, such as: new interface, control layout , get row , get column , a certain row expansion coefficient , a certain column expansion coefficient , a certain column minimum width , a certain row minimum width , total number of cells , remove layout items , move layout items , other articles , etc.
In actual development, an interface may contain more than a dozen controls, and manually adjusting their positions is time-consuming and laborious. The layout manager can do two things: automatically adjust the position of the controls, including the spacing between controls, alignment, etc.; when the user resizes the window, the controls located in the layout manager will also be resized accordingly, thus maintaining the entire interface beautiful.
There are currently 24 articles in this series of QT comprehensive and detailed articles. This series of articles describes the basic operation and use of QT controls in more detail. Thank you for your attention, likes, and collections.
