I am using a wx.listctrl inside a wxpython GUI. I have a list that updates when I click a button. Currently when I select an item and click the button, I do the following:
item = self.my_list.GetItem(row_in_list)
self.my_list.SetItemTextColour(row_in_list,'red')
In addition to turning the font red, I would like to "cross it out" or "strikethrough". I have found wx.FFont(8, wx.FONTFAMILY_SWISS, face='Tahoma', flags = wx.FONTFLAG_STRIKETHROUGH) but this does not seem to work. Any one have ideas? Thanks!
As far as I can tell, strike-throughs are not supported in the ListCtrl widget itself. You would have to create some kind of custom widget or switch to using the aforementioned UltimateListCtrl, which is a very flexible pure Python widget. You can see it in action in the wxPython demo package or read about in the following links:

What I want is a mean to remove an item from the combobox without having to add a separate remove button somewhere else. So I want a remove button to appear at the right side on a combobox dropdown item when I hover over my mouse pointer on it. And, it is also OK if all the items have remove button at the right side and do not need hovering.
The images bellow will illustrate what I am saying [...please ignore my mspaint skils]

The wx.ComboBox does not have this feature. The wxPython GUI toolkit uses the target platform's native widgets. If those widgets don't support doing it, then neither does wxPython.
However, wxPython does have custom widgets or you could create your own widget to do this sort of thing.
I also think you could use a context-menu for this task. You would need to right-click to make it work. Another method would be to bind to a mouse event and try to figure out where in the widget you are, but I think that method would be error prone.
So i'm programming python program that uses wxPython for UI, with wx.TreeCtrl widget for selecting pictures(.png) on selected directory. I would like to add hover on treectrl item that works like tooltip, but instead of text it shows bitmap picture.
Is there something that already allows this, or would i have to create something with wxWidgets?
I am not too familiar with wxWidgets, so if i have to create something like that how hard would it be, lot of code is already using the treectrl, so it needs to be able to work same way.
So how would i have to go about doing this? And if there might be something i might be missing id be happy to know.
Take a look at the wx.lib.agw.supertooltip module. It should help you to create a tooltip-like window that displays custom rich content.
As for triggering the display of the tooltip, you can catch mouse events for the tree widget (be sure to call Skip so the tree widget can see the events too) and reset a timer each time the mouse moves. If the timer expires because the mouse hasn't been moved in that long then you can use tree.HitTest to find the item that the cursor is on and then show the appropriate image for that item.
I am looking to know what is the best practice to make a window which the content changes, but without changing the window. Something like using tabs, but with no tabs, controlled with buttons.
What widget should i use to archive what i need?
And if you don't mind the little off-topic, should it be drawn manually or with a GUI designer like glade?
It is meant to be used within python.
If you can use GTK 3.10, take a look at GtkStack and GtkStackSwitcher. If not, use GtkNotebook and set the show_tabs property to False, then build your own buttons.
I want to create buttons dynamically
self.ctset = wx.BitmapButton(panel, -1, self.pic1, pos=(10,10), size=(50,50))
self.ctset.Bind(wx.EVT_BUTTON, self.add_ct)
self.ctset.SetDefault()
and the add_ct binding function
def add_ct(self, event):
pos=(10,self.yct)
self.yct+=65
self.new = wx.BitmapButton(self, -1, self.pic1, pos=pos,size=(50,50))
self.new.SetDefault()
print "Cutset"
I don't know where I am going wrong but my dynamically created buttons always seem disabled!
I want to bind a function to the dynamically created buttons that allows me to drag them around. Any ideas would be of great help!
I am pretty new to python and wxpython.
I don't see any code that captures the mouse's coordinates or even any drag-and-drop code. You need to download the wxPython demo package from the wxPython website and look at the ShapedWindow example for catching mouse coordinates. See also this old thread: http://wxpython-users.1045709.n5.nabble.com/Drag-Button-around-a-Panel-td3358640.html
In it you will find someone who is doing something very similar to what you want. I also found the following links which you might find helpful:

How to move items smoothly in wxPython?
I'm studying the Tkinter Listbox widget and have been unable to find solutions for the following functionality:
How can I create non-selectable horizontal separator items, eg. separators equivalent to the Tkinter Menu widget's .add_separator()? (Using chars like dashes and underscores looks awful).
How can I disable a specific item? I tried using .itemconfig( index, state='disabled' ) without success.
How can I enable keyboard navigation, eg. when a user's keyboard input automatically scrolls one forward to the closest item that begins with the text the user typed? Must I bind(<KeyPress>, ...) and manage this behavior myself?
Would some of the above functionality be easier to implement using a Text widget or the ttk.Treeview widget?
you cannot. The widget doesn't support that.
you can't disable certain items, the widget doesn't support a state attribute. That being said, you can monitor the selection and do the appropriate thing if the user selects something that is disabled, and use the item foreground to denote disabled-ness.
You will need to bind to keypress events and manage the behavior yourself. It's not particularly difficult, just a little tedious.
the text widget might be your best bet, though you'll have to add bindings to mimic the default bindings of the listbox.
Bottom line: Tkinter provides nothing that directly supports what you want to do, but the building blocks are all there. You'll just have to build it yourself.
