Where does the code for a new slot created using QT designer go? -

i total newbie qt.

i working qt 4.7.1 on visual studio 2008.

i trying implement button covered image, , when pressed, image changes. (image-button) trying use qt designer put button in currect layout programmatically handle pressed event (..signal..) change icon on button.

create new mainwindow. put tool button in it. switch slots&signals mode. created signal-slot button pressed() new slot1() on window. put code of slot1()?

sry english. rly bad, i'll try you.

you have use inheritance approach. so:
• created form, added connection slot1() on form.
• include form in project, compile it. file named ui_formname.h generated. @ bottom of file find code like:
namespace ui {
class mainwindow: public ui_mainwindow {};
} // namespace ui

you have to:
1) create new class, inherit class qmainwindow.
2) in header include generated h-file, add member of type ui::mainwindow, declared in generated .h-file (e.g.: ui::mainwindow* m_puitmp; ).
3) add code:
public slots: // or private slots:, or protected slots: ... whatever.
void slot1();

then create implementation functions in new class. don't forget add m_puitmp->setupui( ); in constructor, , create implementation slot1() slot.

you can describe slots , signals in derived class, , connect them signals , slots in qtdesigner. when adding slot or signal in designer, rename them in accordance names, set in code.

hope you. if can't solve problem, write me message. i'll try help.
