1 | \section{\class{wxClipboard}}\label{wxclipboard} | |
2 | ||
3 | A class for manipulating the clipboard. Note that this is not compatible with the | |
4 | clipboard class from wxWindows 1.xx, which has the same name but a different implementation. | |
5 | ||
6 | To use the clipboard, you call member functions of the global {\bf wxTheClipboard} object. | |
7 | ||
8 | Call \helpref{wxClipboard::Open}{wxclipboardopen} to get ownership of the clipboard. If this operation returns TRUE, you | |
9 | now own the clipboard. Call \helpref{wxClipboard::SetData}{wxclipboardsetdata} to put data | |
10 | on the clipboard, or \helpref{wxClipboard::GetData}{wxclipboardgetdata} to | |
11 | retrieve data from the clipboard. Call \helpref{wxClipboard::Close}{wxclipboardclose} to close | |
12 | the clipboard and relinquish ownership. You should keep the clipboard open only momentarily. | |
13 | ||
14 | For example: | |
15 | ||
16 | \begin{verbatim} | |
17 | // Write some text to the clipboard | |
18 | if (wxTheClipboard->Open()) | |
19 | { | |
20 | // This data objects are held by the clipboard, | |
21 | // so do not delete them in the app. | |
22 | wxTheClipboard->SetData( new wxTextDataObject("Some text") ); | |
23 | wxTheClipboard->Close(); | |
24 | } | |
25 | ||
26 | // Read some text | |
27 | if (wxTheClipboard->Open()) | |
28 | { | |
29 | if (wxTheClipboard->IsSupported( wxDF_TEXT )) | |
30 | { | |
31 | wxTextDataObject data; | |
32 | wxTheClipboard->GetData( data ); | |
33 | wxMessageBox( data.GetText() ); | |
34 | } | |
35 | wxTheClipboard->Close(); | |
36 | } | |
37 | \end{verbatim} | |

53 | \membersection{wxClipboard::wxClipboard} | |
54 | ||
55 | \func{}{wxClipboard}{\void} | |
56 | ||
57 | Constructor. | |
58 | ||
59 | \membersection{wxClipboard::\destruct{wxClipboard}} | |
60 | ||
61 | \func{}{\destruct{wxClipboard}}{\void} | |
62 | ||
63 | Destructor. | |
64 | ||
65 | \membersection{wxClipboard::Clear}\label{wxclipboardclear} | |
66 | ||
67 | \func{void}{Clear}{\void} | |
68 | ||
69 | Clears the global clipboard object and the system's clipboard if possible. | |
70 | ||
71 | \membersection{wxClipboard::Close}\label{wxclipboardclose} | |
72 | ||
73 | \func{bool}{Close}{\void} | |
74 | ||
75 | Call this function to close the clipboard, having opened it with \helpref{wxClipboard::Open}{wxclipboardopen}. | |
76 | ||
77 | \membersection{wxClipboard::GetData}\label{wxclipboardgetdata} | |
78 | ||
79 | \func{bool}{GetData}{\param{wxDataObject\&}{ data}} | |
80 | ||
81 | Call this function to fill {\it data} with data on the clipboard, if available in the required | |
82 | format. Returns TRUE on success. | |
83 | ||
84 | \membersection{wxClipboard::IsSupported}\label{wxclipboardissupported} | |
85 | ||
86 | \func{bool}{IsSupported}{\param{const wxDataFormat\&}{ format}} | |
87 | ||
88 | Returns TRUE if the format of the given data object is available on the clipboard. | |
89 | ||
90 | \membersection{wxClipboard::Open}\label{wxclipboardopen} | |
91 | ||
92 | \func{bool}{Open}{\void} | |
93 | ||
94 | Call this function to open the clipboard before calling \helpref{wxClipboard::SetData}{wxclipboardsetdata} | |
95 | and \helpref{wxClipboard::GetData}{wxclipboardgetdata}. | |
96 | ||
97 | Call \helpref{wxClipboard::Close}{wxclipboardclose} when you have finished with the clipboard. You | |
98 | should keep the clipboard open for only a very short time. | |
99 | ||
100 | Returns TRUE on success. This should be tested (as in the sample shown above). | |
101 | ||
102 | \membersection{wxClipboard::SetData}\label{wxclipboardsetdata} | |
103 | ||
104 | \func{bool}{SetData}{\param{wxDataObject*}{ data}} | |
105 | ||
106 | Call this function to set the data object to the clipboard. This function will | |
107 | clear all previous contents in the clipboard, so calling it several times | |
108 | does not make any sense. | |
109 | ||
110 | \membersection{wxClipboard::UsePrimarySelection}\label{wxclipboarduseprimary} | |
111 | ||
112 | \func{void}{UsePrimarySelection}{\param{bool}{ primary = TRUE}} | |
113 | ||
114 | On platforms supporting it (currently only GTK), selects the so called | |
115 | PRIMARY SELECTION as the clipboard as opposed to the normal clipboard, | |
116 | if {\it primary} is TRUE. | |
