cocoa touch - UIWebview Previous / Next -

-

In my project (iPhone app) I have a good webview that allows users to browse certain websites and I have past / next buttons like any browser.

How do I know if I have previous or next pages, so can I disable one of those two options?

There are properties on the UIWebView: 

  @property ( Nonatomic, readonly, getter = canGoback) BON can be Goback @property (nonatomic, readonly

They are boats which do not return yes or no depending on either direction Whether or not to navigate pages.

As it is very clear that there is no vivestate and there is no postback.

Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);
