I crate one UserControl name as MYUC after then i want to remove that UserControl. what should i do for that.
Maybe there's more to this question than what's literally be asked? However I would think just deleting the UserControl you're talking about is all that would be required to remove it. Unless maybe this is a trick question somehow?

I want to create an Help page for my wxWidgets application, which consists of only text of various fonts, sizes and colors. I tried achieving that with wxStaticText's and sizers but I was having trouble so I switched to a wxRichTextCtrl, which I like to use. The problem is, the text should of course be non-modifiable. I know of the existance of the wxRE_READONLY flag, but it doesn't hide the caret that appears when I click on the text.
Isn't there some kind of wxRichStaticTextCtrl that works exactly like a wxRichTextCtrl, but is readonly by default and doesn't have this problem? I tried looking online, but to no avail.
The best solution for "rich" static text is wxHtmlWindow: this allows you to just define your help contents in terms of simple HTML which is usually more than enough.
I have looked, but am unable to find anything which makes me think I'm approaching this the wrong way.
When I update the content in a template, or display a new template, I want to animate the transition. Currently the content switches but I'd like to be able to use Greensock or similar to perform the change. I have Greensock working on elements fine, but not on templates.
I'd show code but I'm not sure where to begin. I'll update when I've at least made a start.
Cheers.

I'm building a nested navigation bar, here is the jsFiddle:
http://jsfiddle.net/3Y8vB/1/
the nested menus are on the third item, "Collezioni": so far so good. But adding Cufon triggers a strange problem: "hovering" the nested menus and going away from them all the way down, the "Collezioni" link disappears!
http://jsfiddle.net/3Y8vB/2/
Well, it doesn't really disappear: it retains the #fff color (:hover) instead of going back to #111 (normal state), and since the background is white too, it "disappears". Going all the way UP (without "hovering" the nested menus) has no problem.
I'm sure it's a Cufon related problem since the first version (without Cufon) is working nice.
Please, can you help to solve this? Thanks in advance
Ok, found the solution here:

Very quick question here. I was wondering if it is possible for me to reference individual tabs from a QTabWidget by number. This will save me a lot of time, as I am generating an unknown number of tabs during run-time. I could not find anything in the QT documentation, but I feel like this is a very basic feature that should be included. I am thinking something like this (not real code just an idea, I realize tabNumber() doesn't exist):
ui->tabArea->tabNumber(12);
If there isn't a public function, perhaps there's some other way? Please don't suggest referencing tabs by name because that is out of the question (potentially 100's of tabs), and I have already tried it.
If you want the tab with a certain index, use widget():
QWidget* tab = tabWidget->widget( index );
I think the setCurrentIndex() method is what you are looking for.
What's the easiest way in terms of coding effort, to change a text property of a Qt4 widget, e.g. QLabel.text, so all HTML tags are removed?
The HTML is simple, typically just one to three tags like or and their closing partners.
If you don't want to use a widget for that, you can use QTextDocument::toPlainText()
QTextDocument doc;
doc->setHtml(htmlText);
doc->toPlainText();
I've used this in the past, although the widget seems like overkill. QtextEdit, the rich text edit block. What makes this work is that the constructor assumes that the string has tags.
QTextEdit htmlText(HtmlText); // HtmlText is any QString with html tags.
QString plainText = htmlTextEdit.toPlainText();
It sounds like you are really just looking for a way to strip HTML tags from a string which is not something specific to Qt widgets (unless you want a solution that can take advantage of the rest of the Qt library). Anyway, there seems to be no shortage of hits when searching for "strip html from string". There seems to be 2 general approaches:
Use a regular expression (here there be dragons)
Use an html parser
You may find a regex that is good enough for your purposes but you will need a proper html parser to do it right.
This stackoverflow question has alot of discussion about the regex option (although the question is looking to strip all tags except links).
Since you are using Qt, this question has an answer with examples of using a parser from that library.
Why not peek under the hood in QTextEdit::toPlainText() source code, and see what is done there?
