Is is possible to place a button inside of a ListCtrl item with wxPython? Right now I have a ListCtrl that has data with a file name and size, and I want the user to be able to click a button, to download the file. If this isn't possible, is there a way to display an image in the ListCtrl, and then make it clickable so that I can bind an action to it?
No. You will have to use "UltimateListControl", a generic list implementation that can attach any kind of widget to rows. Check its demo files for examples.
You're probably best off grabbing the trunk code for bugfixes and other changes - I'm not sure how often Andrea updates the main zip on his site
I've yet to use the control, but its demo is very impressive.

I don't know How structure the GUI of my program...
I don't have big experience with GUI programming, i know all the widgets, the
geometry managers, the "object-oriented" method in Tkinter, but i don't understand
how combine all this things...
I want to create a program with an image in background where there is a button and if i press this button i switch in another page and the button disappears
Like this : https://moqups.com/iampirla#gmail.com/wyM7CyET/p:a80e8d902
How i can structure my code to do this?
You could use pack_forget() this removes the widget although allows you to use it later if you wish. You could do the first page and then use some code like below. To clear the page. This could then reference the next thing you wish to do using in this example question().
def answred():
nameLabel.pack_forget()
nameEntry.pack_forget()
nameButton.pack_forget()
classQuestion.pack_forget()
button1.pack_forget()
button2.pack_forget()
button3.pack_forget()

You could this but not remove the background widgets
I am trying to build a GUI which will:
Load a file with parameters which describe certain type of problem.
Based on the parameters of the file, show only certain tab in QTabwidget (of many predefined in Qt Designer .ui)
I plan to make a QTabwidget with, say 10 tabs, but only one should be visible based on the parameters loaded. Enabling certain tab is not an option since it takes to many space and the disabled tabs are grey. I do not want to see disabled tabs.
Removing tab could be an option but the index is not related to a specific tab so I have to take care of the shift in the indices. And furthermore if user loads another file with different parameters, a good tab should be added and the current one removed.
My questions are:
How to do this effectively?
Is it better to use any other type of widget?
In Qt designer, is it possible to define many widgets one over another and then just push the good one in front. If yes, how? And how to edit and change any of them?
If using RemoveTab, how to use pointers on tabs, rather than indices?
I use PyQt4
Use a QStackedWidget, which is exactly the same as a tab-widget, but without the tab-bar (which you don't need).
This widget is available in Qt Designer. The context menu has several commands for adding/removing pages and so forth. Note that the arrow buttons in the top-right corner are just there for convenience: they won't appear in your application.
Pages can be added/removed at runtime with addWidget/removeWidget:
index = self.stack.addWidget(self.page1)
self.stack.removeWidget(self.page1)
You can access the pages using either indexes or widget references.
I see that this thread is kinda old. But I hope this will still help.
You can use the remove() method to "hide" the tab. There's no way to really hide them in pyqt4. when you remove it, it's gone from the ui. But in the back end, the tab object with all your settings still exist. I'm sure you can find a way to improvise it back. Give it a try!
I am looking for a way to create breadcrumbs with pyqt. So I have a main panel which loads few attributes. the header and footer remains the same for all the panels.So now in the first panel when I click on a button it takes me to the second panel. So I am looking for something like Panel1->Panel2 which is to be shown in the bottom and when I click on Panel1 it should take me to panel1.Could you let me know how I can achieve it.
You can use the qbreadcrumb widget for this. Though it is not well documented, you can download and customize it according to your needs.
I would like to implement a swipe or flipper view (widget) using PyGtk for my Quickly app. There should be a titlebar that contains the title of the currently showed content and the titles of the previous and next entry. To navigate threw the different entries you should be able to click the titles or swipe from left to right or vice versa.
But I do not know where to start.
Which Widget should I extend?
Would the Notebook widget the right choice?
How could I change the style of a Widget?
How do I implement the flip effect?
Do I have to combine different views (widgets) for the content pane and the titlebar?
For a better understanding of my problem view the screenshot below.
Thanks and best regards

You might want to take a look at Clutter. Though I think, this kind of UI-Design could be very unintuitive on a desktop machine.
I'm new to QT. I'm using PyQT for GUI development in my project. I want to achieve this layout in my application. This application searches images from an image database. Google image search layout is ideal for my purpose.
I'm following the book "Rapid GUI Programming with Python and Qt" and I'm familiar with layouts. I guess I need to use a grid layout with each result image in each box of grid. & use vertical layout for (image,Qlabel,Qlabel) inside each grid box.
These are some problems I'm facing.
Importantly, I'm unable to display image. What control/widget do I need? I cannot find anything similar to PictureBox of .NET
How do I seperate these image result by fixed gap like in the image? I'm using Horizontal & vertical spacers but that isn't working?
How to set QLabel a clickable (like hyperlink). I don't want to a open a URL. Just the text should be clickable. So, that when user clicks on the link. I can show more information (like next set of results when he clicks on next page number or a new window with image in fullsize when user clicks on 'view') Do we have some new kind of control for this?
This is another important issue. I'll display the page numbers of results (like shown in figure) & assuming they are clickable. How do I load a new page of results? I mean what is the equivalent of page in QT?
As you can guess. This definitely wont be the first page of GUI. The first page will be exactly like http://google.com (a big logo & text box with button below it). when user clicks the search button. This page will be displayed. Again the same question comes up. How change the pages?
Please give a list of controls I'm going to need for this. Tell me if I'm unaware of something.

For displaying the images and labels use a QListWidget with view mode set to QListView::IconMode. However, if you need to customize the display beyond what the QListWidget/QListWidgetItem api can provide you will need to create your own QAbstractListModel and use a standard QListView with it.
Make sure and read Qt's primer on model/view.
As for spacing the images, checkout the spacing property on the list view.
Here is an example from KDE's Dolphin file manager:
3. Use a regular QLabel, but set the contents to be an href.
Example:
edit: Oops I see from your tags you are using PyQt, the following is C++, but should be similar to what you would do in python.
QLabel *linkLabel = new QLabel;
linkLabel->setTextFormat( Qt::RichText )
linkLabel->setText( " Click me! " );
connect( linkLabel, SIGNAL( linkActivated ( const QString & link ) ), .... )

Well, since you are using a Model/View, why bother having page numbers at all? The user will just be able to scroll the view and more pictures will be shown. This is by far the easiest solution as you don't have to do anything once you've got your M/V setup!
However, if you really want to show page numbers it will require more work in your model. For example, have a track the "current page" in the model and only allow access to images on the "current page". Then in your slot connected to the linkActivated() signal tell the model to change pages. I won't go into much more detail as this seriously violates the whole idea behind model/view. The "right way" of doing this would be to subclass QListView and add pagination support, but like I said why not use scroll bars? There isn't any performance hits to doing so.
5. Use a QStackedWidget, addWidget() all your "pages" to it, then call setCurrentIndex/Widget() as needed to switch the pages.
Thoughts:
It seems you are very committed to cloning the look, feel, and behavior of Google Image search, which is fine, but Google Image Search is a web application that uses interaction paradigms that are very different than a normal desktop application (links, pages, etc). You are presumably developing a desktop application, and by trying to emulate the behavior of a web app you will find it difficult as the API just isn't designed to support those sorts of interactions. By all means, it is doable, but you'll have your work cut out for you.
If you are extremely intent on sticking to the web based interaction style, why not code your app in javascript and HTML and toss it in a QWebView?
Try using QListWidget with viewMode set to IconMode. It should do all for you. BUT if you need to customize your data display use QListView with your own/standard model and own delegate for painting
