A structure position, for example, how the FORM1 and FORM2 share, modify the data?
Struct position {
int x;
Int y;
Float p;
};

Position the position [17] [41] [20].

CodePudding user response:

Contains the other side of the header file should be ok,

CodePudding user response:

No, I also defines the variables and the structure
For example,
Struct position {
int x;
int y;
Float p;
};
Position the position [17] [41] [20].
Int ABC;
Modify the ABC in FORM2 form, see in the FORM1

CodePudding user response:

Modify the ABC in FORM2 form, in FORM1
See ABC has changed, but modify the position [0] [0] [0], z
Do not change,

The

modify the ABC in FORM2 form, in FORM1
See ABC has changed, but modify the position [0] [0] [0], z
Do not change,

The code posted a look

CodePudding user response:

Put the following code in a. H file, contain the two window. H file
Struct position {
int x;
int y;
Float p;
};

Extern position position [17] [41] [20].//declare external variable
One of the window, define the position again position [17] [41] [20].
In this way, the position [17] [41] [20]. In the project is global

1. Define a global variable
2. A class is defined as the public, another class to access the class - & gt; XXXX

CodePudding user response:

Two form Shared variables, containing each other header files, and then in their respective variables declared in a header file, defined in the CPP files can,
For example: Unit1 structure of A variable is A need to share, Unit2 of the variable structure B B need to share, so:
Unit1. H file

 struct A 
{
. 
}; 
Extern A, A. 

Unit1. CPP file

 A, A. 

Unit2. H file

 struct B{
. 
}; 
Extern B B; 

Unit2. CPP file

 B B; 

And then in Unit1 and Unit2 can use a and b,

CodePudding user response:

I tend to be
Use in Form2 Form1 - & gt; A,
Use in Form1 Form2 - & gt; B,
Such use ok?
