Kivy Screen Changing -

-

OK guys, I have a problem, I want to click on a button on the popup and then click on the popup It should transcise another screen .... here my code just wants to get a new fresh screen when I click on the popup button kivy.app Import from app popup from kivy .uix.gridlayout Import from kivy.uix.label import from kivy.uix.textinput Import label by kivy.uix.button Import button from TextInput ki vy.uix.boxlayout import box from # kivy.uix.stacklayout from stackLayout kivy from import.in screenmanager import screenmanager, screen class login screen (grid layout, screen): def __init __ (self, sm, ** kwargs): Super (login screen, self) .__ init__ (** kwargs) self.sm = sm self.cols = 2 self.row = 2 self.add_widget (label (text = 'user name', font_size = '20sp') ) self.username = TextInput (multiline = False) self.add_widget (self.username) self.add_widget (label (text = 'password')) self.password = TextIn (password = true, multiline = folose) self.ad_visit ( Self. Password) Self.add_widget (self.hello) def save (self). Hello = Button (text = "hello", onpress@lambdaA: self defense (), size = (100, 100), size_hint = (0.3, 0.3) ): Print ("s") id_name = self.username._get_text () id_num = self.password._get_text () if id_name == "Hendricko" and id_num == "stokkies123": content = button (text = "press here Popup = popup (title = "you may proceed", content = content, size = (50, 50), size_hent = (0.3, 0.3), size = (100, 100) , Auto_discism = false) content.bind (on_press = lambda b: self.check_menu_press) popup.open () def check_man _press (self, button, * args): if buttons.txt == 'normal': self.sm.current = "secondscreen" class seconds (grid layout, screen): def __init __ (self, sm, ** kwargs) : Super (secondscreen, self) .__ init __ (** kwargs) self.row = 2 self.cols = 2 self.add_widget (label (text = "hello", font_size = "20sp")) self.sm = sm def on_touch_down (auto, touch): self.sm. Current = "login screen" class My AP (creation of DEF): Def (self): SM = ScreenManager () sm.add_widget (login screen (SM, name = "secondscrin")) sm.add_widget (seconds screen (SI, name = "Login screen")) Return to ST if __name__ == '__main__': MyApp () Run ()

content .bind (on_press = lambda b: self. check_menu_press)

This lambda function does nothing. You probably mean content.bind (on_press = lambda b: self.check_menu_press (b)) . I think it would be neater to use functools.partial , however, if you want to work in this way.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
