You should be fine to build Qt for Unix/X11 under either of these environments and then build your app against that.

Re: [Interest] HTML5 canvas support?
To answer your questions, 1. No, You'll have to use CSS and such to style them, and come up with specific POST handlers for every possible input. If that's what you want then use Wt. The advantage here is that there is only ever one POST handler, which handles browser events like KEY UP/DOWN, and MOUSE MOVE, BUTTON UP/DOWN. Another advantage is you can style it using Qt Style Sheets. Really I made this so I could put a legacy Qt application on the web. No [Adobe] plugins required! 2. UI Files, as made by Qt Designer or Creator. 3. Don't worry about the license. My thing is that I want something for my resume. And I didn't want people finishing it before I had a better effort in place. With GTK's Broadway already complete, I will be creating Vaudeville, the Qt version, as soon as I get time and 5.0 is out (QPA interfaces will be 'finalized').

Jason, I think it's cool. I would have been nice if you had at least included the private files needed, but I hunted them down and got it working;) I'm trying to build Qt remotely on a web server so I can try to use it for CGI scripts so maybe your concept will come in handy. I'm not very familiar with some of Qt's web capabilities but wouldn't it make more sense to generate actual html checkboxes and radiobuttons for some of that? I can see some interesting uses for the canvas but was wondering if there is anything else that does say an entire html page layout? Is this uncharted territory or can Qt already do this? Your license is a little odd. Why don't you just include your email in the files and state that your releasing the code into the public domain or just use the zlib license: http://www.gzip.org/zlib/zlib_license.html Sorry for such a delayed response on this.

Re: [Interest] ICS Announces Qt-Based Google APIs
I took a quick look at qt-google-calendar, but it's unclear to me how the authentication is supposed to work? Basically the code expects you to fill in response uri, but does not implement the server for it? What am I supposed to put in there (m_strRedirectURI)?Reading google docs it should probably be http://localhost:port but then I should have a server listening there (or oauth2 should provide one).

Re: [Interest] Dynamically Resizing the height of a Row in a QTableWidget or QTableView
Hello Mike, I am not sure about dynamically resizing the row height, but I have a suggestion that you may or may not find helpful... Instead of placing the entire portion of text in the table cell, why not use the QFontMetrics::elidedText(...) function to add ellipsis to the left, right or middle of your text and then set the tooltip on the cell to show the entire text when the text is too long? Hope this helps...

Re: [Interest] QAbstractItemView and default QItemSelectionModel
Thanks Andreas! I know it doesn't exactly answer my question, but you are
right, I can easily check this and I probably should just do the right thing
anyway and delete it. However, this suggestion:
Or you could make sure the selection model is set before the model, so that no
default-selection-model is created at all
I am curious about this because according to the Qt documentation on
QAbstractItemView::setSelectionModel this would not work. Maybe I am misreading
what it says though. Here is what it reads:
Note that, if you call
setModelhttp://doc.trolltech.com/4.7/qabstractitemview.html#setModel() after
this function, the given selectionModel will be replaced by one created by the
view.
Do you think I am not reading this incorrectly?

Hello All,
I have a curious question about the default QItemSelectionModel that is created
whenever a QAbstractItemView is created: Is this default selection model
parented to the view? What I really want to know is, if I create a new
QAbstractItemView, set the model on it and then create a new
QItemSelectionModel and pass it into the view's setSelectionModel() function,
will the default selection model be deleted when the view is deleted? The
documentation is a little hazy on this topic. It says that It is up to the
application to delete the old selection model if it is no longer needed...,
but that it will be deleted by its parent if it has one. So, I have a new view
and I am changing its selection model to my own and the one that was created by
default is no longer needed. Should I go ahead and delete the old default
selection model, or is it safe to say it is parented to the view and will be
deleted when the view is deleted?
You could just test what your version of Qt does with:
QAbstractItemView view;
QStandardItemModel model;
view.setModel(model);
QItemSelectionModel selmodl = view.selectionModel();
if( selmodel.parent() == view ) {
fprintf(stderr, selection model is parented under view\n);
} else {
fprintf(stderr, selection model has unknown/no parent\n);
}
Since the documentation does not state what behaviour is to be expected, you
shouldn't rely on this however. Since in this case I can't imagine any possible
bad side-effects of deleting the model even if it is parented under the view,
you could just be a little less lazy and delete the selection-model before
setting a new one. Or you could make sure the selection model is set before the
model, so that no default-selection-model is created at all.

[Interest] Most direct path to using a QComboBox to edit a cell in a QTableView?
Hello List! I have a QTableView and I would like to use a QComboBox to insert and modify its entries. I'm looking for the simplest way to do this that uses as much unmodified Qt functionality as possible. At the moment I am thinking that I can use the class template QStandardItemEditorCreator specialized on QComboBox as the most direct way to do this. Two questions: Am I on the right track here? What specifically do I need to do to make this work? I don't really see the full end-to-end logic (i.e., starting with a specific instance of a QTableView) of how to hook all of the plumbing together. (The model backing the QTableView happens to be a QSqlTableModel, although -- and please correct me if I'm wrong -- this should be irrelevant.) I've looked at a number of examples in the Qt documentation but the ones I've found seemed to be concerned with writing custom delegates and editors, rather than using existing delegate and editor classes already provided by Qt. Although I do believe I could achieve my end goal with a custom delegate, I think using one would be more complicated than necessary. For example, as I understand it, QTableView uses QItemDelegate as its default delegate, and that I can achieve my goal without changing this. Assuming that I am on the right track, concrete details would be greatly appreciated. I'm lost in the multiple layers of the documentation at the moment. Thanks for any suggestions. K.

Re: [Interest] Most direct path to using a QComboBox to edit a cell in a QTableView?
Hi Frank, What does the standard delegate do for your model/view at the moment? I can't recall the specifics, but it certainly uses combo boxes at the moment - eg, for boolean fields (which I think is painful, but anyway). I think you need to give more information about what you are expecting. For example, you include 'insert' as an action. But what does this mean? If a user types an entry not already in the list, what do you expect to happen? Which table would the new entry be inserted into? Where should the combo box get its values from? Yes I agree that the model view classes take a while to grok. Tony. Sent: Tuesday, 26 June 2012 2:36 PM Hello List!
