value type of the function as const; In addition to overloading operators, it is generally not to make the return value type a const reference to an object; [Study Questions Answer]1 This method is incorrect, because the purpose of the declaration pointer is to change the content it points to, and the declared pointer e points to a constant, so it is incorrect;2 This method is correct, because the content of the declaration pointer is variable;3 This practice is not correct;In const a:

Setcontentsmargins () method, which is prototyped as follows:Voidqlayout::setcontentsmargins (int left, int top, int right,int bottom)Among them, left, top, right, and bottom represent the white space around the layout.For Qgridlayout and qformlayout, do not use the setspacing () method, but instead use the sethorizontalspacing () and setverticalspacing () methods to set the spacing between the horizontal and vertical directions, respectively. If you use the Setspacing () method and get spacing

From the principle of execution, is completely consistent.By grasping this point, it is easier to understand the running mechanism of the MFC program.The main function in C is equivalent to the winmain function in MFC.If you are interested, you can use the breakpoint settin
