Creating a structure that pops multiple child windows from a window is called an MDI form structureIf you do not manage by MDI structure, the simplest approach is:Add a menu or button on form A to add a pop-up B-form code to a menu or button event:b b = new B ();B.show ()So that A and B have no relationship, how many pop-up windows on the taskbar have the number of icon
Avoid new MDI child resizing animation (and delay) in Delphi MDI applications

If you are creating MDI applications using Delphi, you must have noticed some "quirks" or issues that you cannot simply handle/fix from your code.

All Windows-based applications have a menu called window, where options can be used to arrange all open windows.In order to arrange the subform that is open in the MDI parent form, you need to write the following code:①this.

The multi-document interface is the so-called MDI, which was introduced from the Microsoft Excel spreadsheet program in Windows 2.0. This is because the Excel spreadsheet user sometimes needs to operate multiple tables at the same time, MDI provides great convenience for such operations on multiple tables, so an MDI program is generated. In Windows 3.1,

Before multi-SDI, the MDI was available. wtl provides a series of related classes based on the cframewindowimplbase base class, which makes it especially easy for programmers to compile the MDI application. Figure9 shows the MDI window architecture of wtl.
