Here is my sample code.I am learning the list view methods,I already posted one question,but i have a small doubt in my program.In my program after "fliter" i am getting the matched items of the word in that i want to choose the selected item using the enter key but it is printing the first item after selecting..I don't want to print the first item of the matched list..can any one please help me.Thank you in advance.
given below is my code:

self.list.setFocus()
else:
self.list.setRowHidden(row, True)
ix = self.list.selectionModel().selectedIndexes()
#here if i mentioned self.list.selectionModel().currentIndex() means it is automatically printing the first item in List_View
# i dont want to print first item ...after slecting the item in list view i will press enter key then only i want to print the selected item name
print ix.data()

finally i got this answer..thq eyllanesc sir,i refer all your previous answers related to list view..Thank you so much..

Here I need to select the green highlighted item using arrow keys without clicking the item
You have to use the currentChanged signal of the selectionModel() of the QListView:

super(MainWindow, self).__init__(parent)
self.lineedit = QtGui.QLineEdit()
self.search_button = QtGui.QPushButton("Search")
self.close_button = QtGui.QPushButton("Close")
self.listview = QtGui.QListView()
model = QtGui.QStandardItemModel(self.listview)
for e in ('one', 'two', 'three'):
model.appendRow(QtGui.QStandardItem(e))
self.listview.setModel(model)
# signals connections
self.listview.selectionModel().currentChanged.connect(self.on_currentChanged)
QtCore.QTimer.singleShot(0, self.selectFirstItem)
# layout
central_widget = QtGui.QWidget()
self.setCentralWidget(central_widget)
vlay = QtGui.QVBoxLayout(central_widget)
hlay = QtGui.QHBoxLayout()
hlay.addWidget(self.lineedit)
hlay.addWidget(self.search_button)
hlay.addWidget(self.close_button)
vlay.addLayout(hlay)
vlay.addWidget(self.listview)
self.resize(640, 480)
def selectFirstItem(self):
self.listview.setFocus()
ix = self.listview.model().index(0, 0)
self.listview.selectionModel().setCurrentIndex(ix, QtGui.QItemSelectionModel.Select)
#QtCore.pyqtSlot(QtCore.QModelIndex)
def on_currentChanged(self, current):
self.lineedit.setText(current.data())

How to modify the combobox in wxPython to dropdown a checklistbox so I can select the choices?
something like above. I know that ComboBox class is available and I need to inherit it add the feature of checkbox to dropdown list. But I am not getting the proper way to start with it.
Take a look at the ComboCtrl class. It allows you to provide the window that implements the combo's drop-down. There are some examples in the wxPython demo.
I haven't had the time to grind through ComboCtrl and it looks daunting.
However, an approximation of what you want can be achieved by torturing a wx.Dialog.
import wx
import wx.lib.scrolledpanel as scrolled

self.button = wx.Button(self.panel, label="Choose Colours")
sizer.Add(self.log, 0, wx.EXPAND | wx.ALL, 10)
sizer.Add(self.button, 0, wx.EXPAND | wx.ALL, 10)
self.panel.SetSizer(sizer)

self.panel.options = ['Red','Green','Black','White','Orange','Blue','Yellow']

dlg.ShowModal()
if dlg.result:

for item in range(len(dlg.result)):
if dlg.result[item]:

self.log.AppendText(result_text+'\n\n')
self.panel.selected = dlg.result
else:

So I have been teaching myself Object Oriented Programming for Tkinter projects as I clearly see that they are much more organized for large amounts of coding. However I must admit that I've been coasting by simply copying various bits of coding from online, not fully understanding what its purpose is.
This has lead me to the point that my code does not work at all and I have no idea why not. The first issue is an issue with simply changing an aspect of other widgets.
I have this sample code:
import Tkinter as tk
LARGE_FONT = ("Verdana", 12)
class SeaofBTCapp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
container = tk.Frame(self)
container.pack(side="top", fill = "both", expand = True)
container.grid_rowconfigure(0, weight = 1)
container.grid_columnconfigure(0 , weight = 1)
self.frames = {}
frame = StartPage(container, self)
self.frames[StartPage] = frame
frame.grid(row = 0, column = 0, sticky = "nsew")
self.show_frame(StartPage)
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text = "Start Page", font = LARGE_FONT)
label.pack(pady = 10, padx = 10)
button = tk.Button(self, text = "Change Label", command = self.change)
button.pack(pady = 10, padx = 10)
def change(self):
label["text"] = "It has changed"
app = SeaofBTCapp()
app.mainloop()
Which SHOULD be a simple enough code that, with a button press, change the label from "Start Page" to "It has changed". But whenever I run it, it says that the global variable "label" is not defined. Additionally, if I then change it to self.label, it states that StartPage instance has no attribute 'label'. I don't know what I'm doing wrong.
Additionally, in a similar vein, I'm working on a project that has a SideBar class and a Main class tied to one MainApplication class. The Main class takes a value and displays it on a Frame in the Main class. Following this, a button in the SideBar increases that value by 1. But the Main display doesn't update and I have no idea how to tie the Main updating with the button in the SideBar.
import Tkinter as tk
something = [0, 6]
class Main():
def __init__(self, root):
mainboard = tk.Frame(root, height = 100, width = 100)
self.maincanvas = tk.Canvas(mainboard, bd = 1, bg = "white")
mainboard.grid(row = 0, column = 0)
self.maincanvas.grid(row = 0, column = 0)
self.maincanvas.create_text(45, 50, anchor = "center", text = str(something[1]))
class SideBar():
def __init__(self, root):
sidebarframe = tk.Frame(root, height = 100, width = 100)
button = tk.Button(sidebarframe, width = 20, text = "Change Value", command = self.add)
sidebarframe.grid(row = 0, column = 1)
button.grid(row = 0, column = 0)
def add(self):
something[1] += 1
print something[1]
class MainApplication():
def __init__(self, parent):
self.parent = parent
self.sidebar = SideBar(self.parent)
self.main = Main(self.parent)
if __name__ == "__main__":
root = tk.Tk()
MainApplication(root)
root.mainloop()
All help would be appreciated, but please try and not use a lot of technical terms, as I am still learning.
In the first scenario replace:
label = tk.Label(self, text = "Start Page", font = LARGE_FONT)
label.pack(pady = 10, padx = 10)
With:
self.label = tk.Label(self, text = "Start Page", font = LARGE_FONT)
self.label.pack(pady = 10, padx = 10)
And also in the function change put it like this:
self.label["text"] = "It has changed"
And in your second problem i changed the code a little bit so it works:
import Tkinter as tk
something = [0, 6]
class Main():
def __init__(self, root):
mainboard = tk.Frame(root, height = 100, width = 100)
self.maincanvas = tk.Canvas(mainboard, bd = 1, bg = "white")
mainboard.grid(row = 0, column = 0)
self.maincanvas.grid(row = 0, column = 0)
self.maincanvas.create_text(45, 50, anchor = "center", text = str(something[1]))
class SideBar():
def __init__(self, root, main):
self.main = main # Putting the main object to self.main
sidebarframe = tk.Frame(root, height = 100, width = 100)
button = tk.Button(sidebarframe, width = 20, text = "Change Value", command = self.add)
sidebarframe.grid(row = 0, column = 1)
button.grid(row = 0, column = 0)
def add(self):
something[1] += 1
self.main.maincanvas.delete("all") # Removing everything from canvas
self.main.maincanvas.create_text(45, 50, anchor = "center", text = str(something[1])) # Inserting the new value
print something[1]
class MainApplication():
def __init__(self, parent):
self.parent = parent
self.main = Main(self.parent) # The main needs to run first
self.sidebar = SideBar(self.parent, self.main) # So that SideBar can use its canvas
if __name__ == "__main__":
root = tk.Tk()
MainApplication(root)
root.mainloop()
I have a wxgrid inside a resizable scrollable panel. I dynamically add/hide/show rows in wxgrid. When I try to add/show more rows in wxgrid, it does not fit to the available space in panel but instead occupies a small area it had been occupying previously with a scrollbar for wxgrid.
Like this:
But after I resize the panel or frame, then it fits perfectly. Like this:
How can I make it to fit properly without needing to resize the panel?
I have tried all combinations of wx.EXPAND, wx.GROW, wx.ALL while adding grid to sizer and also tried gridobj.Layout() Nothing works. Any Ideas?

To simulate:
1. run main.py It displays a splitted window with a grid with single row in one panel.
Use the drop down to select more than one item (hold ctrl and select)
The wxgrid is cramped to one row space with a wxgrid scrollbar
Resize the panel using the splitter or resize the window. Now all the selected rows appear as required.
Finally found out!!!
With the help of This Answer, found that the problem was trying to redraw the gridpanel using gridpanel.Layout(). Instead redrawing the gridpanelsizer using gridpanelsizer.Layout() worked out!!
Updated main.py:

A great tool to debug this is the WIT (http://wiki.wxpython.org/Widget%20Inspection%20Tool)
With your corrected code I can get it to grow by forcing the sash position, not ideal, but it shows that the 'problem' is with the splitter.
