connections between two forms

[sudheer]

hi,
how should i open a form(2) by clicking the button on the form(1)

i had made this in qt3.3 easily like ( form2 dialog1( this );
dialog1.exec();
)

but it is little confusing in qt4.3.2

That code is valid in 4.x too. What problems did you encounter?

this is my problem, i am also attaching my program

/************************************************** *****
test5.cpp: In member function `void test5:peninternet()':
test5.cpp:21: error: `dialog1' undeclared (first use this function)
test5.cpp:21: error: (Each undeclared identifier is reported only once for each function it appears in.)
test5.cpp:21: error: expected `;' before "inter1"
test5.cpp:22: error: `inter1' undeclared (first use this function)
*/

in header file i have included form2 header file, but though it giving error

Who is dialog1? You haven't declared it anywhere. I assume you want to show the dialog defined by dialog1.ui. You have to implement it - do as you did for the main window.

Since you use exec() to show the dialog, you can create the dialog on the stack(declare it as variable in that function).
