Create Applications and/or Dialogs

By selecting "Main Window" or "Dialog" from the Main Form, tk_happy will create python source code for either a main-window type application or simply a dialog that will be called from an application.

Each project is given a name and tk_happy will save results files with the project name as a file prefix. A project named "myApp", for example, will save tk_happy information to "myApp.def". If the project is a "Main Window", the python source code will be saved to "myApp.py". If "Dialog" is selected, the python source code will be saved to "myApp_Dialog.py".

An example of source code created for a "Main Window" is shown on this sites web page "Python Source". The following is the bottom of a python source file for a dialog. If the dialog file is run stand-alone, then a test application is run that calls the dialog.

Notice that the test function prints the results of the dialog with the line "print dialog.result"

class _Testdialog:
    def __init__(self, master):
        frame = Frame(master, width=300, height=300)
        frame.pack()
        self.master = master
        self.x, self.y, self.w, self.h = -1,-1,-1,-1

        self.Button_1 = Button(text="Test Dialog", relief="raised", width="15")
        self.Button_1.place(x=84, y=36)
        self.Button_1.bind("<ButtonRelease-1>", self.Button_1_Click)

    def Button_1_Click(self, event): #click method for component ID=1
        dialog = _Entry(self.master, "Test Dialog")
        print '===============Result from Dialog===================='
        print dialog.result
        print '====================================================='

def main():
    root = Tk()
    app = _Testdialog(root)
    root.mainloop()

if __name__ == '__main__':
    main()

The "validate" function returns the result of the dialog.

The default for tk_happy is to return a dictionary from the dialog, however, the user can change the return value to anything they want.

    # tk_happy generated code. DO NOT EDIT THE FOLLOWING. section "dialog_validate"
    def validate(self):
        self.result = {} # return a dictionary of results

        # >>>>>>insert any user code below this comment for section "dialog_validate"
        # set values in "self.result" dictionary for return
        # for example...
        # self.result["age"] = self.Entry_2_StringVar.get() 


        self.result["info"] = self.Entry_1_StringVar.get()
        return 1

tk_happy will create dialogs as well as applications.
