There are two buttons in my little program, start and stop. And what I want is to disable the start button after I click it, and when I hit the stop button it should return to normal. How can I do this? I googled for a while and couldn't find the answer, hope you guys can help me out.
Thanks!
Use the button's Enable and Disable methods in the appropriate event handlers. There's a sample available at the link below:
wxPython Button Demo
In this snippet we are playing around with wxPython's buttons, showing you how to bind the mouse click event, enable and disable, show and hide the buttons. Each button also has a tool-tip (hint) associated with itself.

When reading events from a simple button in PySimpleGui, spamming this button with mouseclicks will generate an event for each of the clicks.
When you try to do the same with Listboxes (by setting enable_events to True for this element) it seems like there is a timeout after each generated event. If you click once every second, it will generate all the events. But if you spam-click it like before it will only generate the first event.
I'm not sure if this behavior is intended (only started learning PySimpleGui today), but is there a way to get rid of this delay? I tried checking the docs but can't find it mentioned anywhere.
I think the reason is that a Listbox reacts to click events, but also to double click events. A Button does not. This behavior looks like consistent.
I found ways to hide something after pressing a button, but what I would like to do is having an invisible button that can still be pushed. A secret button of some sort, using Tkinter. It doesn't need to do anything yet
You don't need an invisible button to register a secret click Simply bind <1> to the root window and it will register whenever you click on anything (unless you click on some other widget that is listening for that event). You can then check the coordinates of the click to see where the use clicked.
I'm trying do a very simple task: Make a Button click in Tkinter.
I have an array of Buttons and, when I finish an event, I want to make a Button click event in one of my buttons.
I thought it should be as simple as buttons[2].click(), but that doesn't do anything.
Try calling .invoke() on the button
I am using a SearchCtrl with a dropdown menu and I'm having some trouble with the events. When I click the little arrow next to the search button, the EVT_SEARCHCTRL_SEARCH_BTN is triggered, which is not what I want. I only want the EVT_MENU_RANGE to be triggered after I clicked an item, and not also the EVT_SEARCHCTRL_SEARCH_BTN before i click it.
self.search_ctrl = wx.SearchCtrl(self.panel_1, -1,
style=wx.TE_PROCESS_ENTER)
self.search_menu = wx.Menu()
self.search_items = {"text1":"value1", "text2":"value2"}
for txt in self.search_items:
self.search_menu.Append(-1, txt)
self.search_ctrl.SetMenu(self.search_menu)
self.Bind(wx.EVT_SEARCHCTRL_SEARCH_BTN, self.search, self.search_ctrl)
self.Bind(wx.EVT_MENU_RANGE, self.onSearchMenu)
Although I should probably add id's to the menu bind, this isn't causing the problem. The code works as expected when I comment out the search button bind.
UPDATE
Apparently this isn't a problem, but a 'feature' of the searchctrl. I tried the wxpython demo and the menu also showed up if I just clicked the search button, and not the arrow. It is apparently one button, instead of the two i thought it was.
Is there a way to accomplish my original request? Do i have to manually modify a textctrl, or is there an other solution?
All the examples I've seen suggest you need to specify a range of IDs when you call your menu bind.
Maybe by default it binds to something unexpected... ?
Edit - In light of your update, it seems likely that you're going to need to make a custom control to me..
I need to add a popup dialog box on my GUI.
So, when ever I hover my mouse over a label, it should be able to show a popup( Like the type we get while hovering over a file in windows).
It should also disappear as soon i move away the mouse.
To start with, I am not even sure which module or class to use. I tried menu, but the results are not what i expected.
I also tried to learn tkCommonDialog, but couldn't understand it properly.
Please Advice!
The little popup window is called a tooltip.

Take a look at the Balloon widget in the Tix package. I think it is just what you are looking for.
