messagebox

The following code runs fine within IDLE, but otherwise I get "NameError: global name 'messagebox' is not defined". However, if I explicitly state from tkinter import messagebox , it runs fine from where ever. from tkinter import * from tkinter import ttk root = Tk() mainFrame = ttk.Frame(root) messagebox.showinfo("My title", "My message", icon="warning", parent=mainFrame) Why does IDLE not need the explicit import statement but elsewhere it is required? the messagebox is a separate submodule of tkinter, so simply doing a complete import from tkinter: from tkinter import * doesn't import

I need a quick text input dialog box (MessageBox with a single text box in it). Is there any control available or should I use a form? I just want user to enter some ID. And in other occasion I want 2 texboxes for username and password. Microsoft.VisualBasic.dll has an InputBox method which you can use from C# to get a single string. For example (Add a reference to Microsoft.VisualBasic.dll first) using Microsoft.VisualBasic; string response = Interaction.InputBox("Enter a string:", "MyApp", "DefaultString", 0, 0); Othewise, you'll have to make your own form. simple one is inputbox 来源： https:/

I want to display a MessageBox alerting the user that the process is complete, and giving a breakdown on how long each stage of the process took. I've got the text that I want to display formatted appropriately, but the default font of the MessageBox class is not mono-width. As far as I can tell, there's no way to specify the font that the text displays with. Is there an out-of-the-box library somewhere that I can use for this, or am I going to have to write one up myself? Any reason not to just create a Form with a textbox/label using a monospace font, then call Form.ShowDialog ? Sounds like

Just now I noticed that Visual Studio shows a message box with details when a property is set to an invalid value. For example: Is it possible to make this type of message box in WinForms? I have tried the following code: MessageBox.Show("Error in Division Fill.\n" + ex.Message, "Information", MessageBoxButtons.OK, MessageBoxIcon.Information, MessageBoxOptions.RightAlign); But this produced the following error: Error 24 The best overloaded method match for 'System.Windows.Forms.MessageBox.Show(string, string, System.Windows.Forms.MessageBoxButtons, System.Windows.Forms.MessageBoxIcon, System

I'm using the MessageBox class to show errors to users, and while that might not be the right behavior, it's very convenient. This is a touchscreen application, however, so I need the 'ok' button to be much larger than it is (curse my inordinately large fingers!). I think that if I increase the font size in the dialog box, I should be ok. Is there a way to do that? Or really, is there any way to increase the dialog size? Thanks As far as I'm aware you can't, as the 'normal' dialog boxes are using your default system font settings. Roll your own is probably the best way forward. It's fairly

In normal Python (3.x) we always use showerror() from the tkinter module to display an error message but what should I do in PyQt5 to display exactly the same message type as well? Qt includes an error-message specific dialog class QErrorMessage which you should use to ensure your dialog matches system standards. To show the dialog just create a dialog object, then call .showMessage() . For example: error_dialog = QtWidgets.QErrorMessage() error_dialog.showMessage('Oh no!') Here is a minimal working example script: import PyQt5 from PyQt5 import QtWidgets app = QtWidgets.QApplication([]) error
