This demo shows some examples of data transfer through clipboard or
|
|
drag and drop. In wxWindows, these two ways to transfer data (either
|
|
between different applications or inside one and the same) are very
|
|
similar which allows to implement both of them using almost the same
|
|
code - or, in other words, if you implement drag and drop support for
|
|
your application, you get clipboard support for free and vice versa.
|
|
<p>
|
|
At the heart of both clipboard and drag and drop operations lies the
|
|
wxDataObject class. The objects of this class (or, to be precise,
|
|
classes derived from it) represent the data which is being carried by
|
|
the mouse during drag and drop operation or copied to or pasted from
|
|
the clipboard. wxDataObject is a "smart" piece of data because it
|
|
knows which formats it supports (see GetFormatCount and GetAllFormats)
|
|
and knows how to render itself in any of them (see GetDataHere). It
|
|
can also receive its value from the outside in a format it supports if
|
|
it implements the SetData method. Please see the documentation of this
|
|
class for more details.
|
|
<p>
|
|
Both clipboard and drag and drop operations have two sides: the source
|
|
and target, the data provider and the data receiver. These which may
|
|
be in the same application and even the same window when, for example,
|
|
you drag some text from one position to another in a word
|
|
processor. Let us describe what each of them should do.
