/**

|
|
Support tip kinds for wxRichToolTip.
|
||
|
|
|
||
|
|
This enum describes the kind of the tip shown which combines both the tip
|
||
|
|
position and appearance because the two are related (when the tip is
|
||
|
|
positioned asymmetrically, a right handed triangle is used but an
|
||
|
|
equilateral one when it's in the middle of a side).
|
||
|
|
|
||
|
|
Automatic selects the tip appearance best suited for the current platform
|
||
|
|
and the position best suited for the window the tooltip is shown for, i.e.
|
||
|
|
chosen in such a way that the tooltip is always fully on screen.
|
||
|
|
|
||
|
|
Other values describe the position of the tooltip itself, not the window it
|
||
|
|
relates to. E.g. wxTipKind_Top places the tip on the top of the tooltip and
|
||
|
|
so the tooltip itself is located beneath its associated window.

/**
|

|
|
Allows showing a tool tip with more customizations than wxToolTip.
|
||
|
|
|
||
|
|
Using this class is very simple, to give a standard warning for a password
|
||
|
|
text control if the password was entered correctly you could simply do:
|
||
|
|
@code
|
||
|
|
wxTextCtrl* password = new wxTextCtrl(..., wxTE_PASSWORD);
|
||
|
|
...
|
||
|
|
wxRichToolTip tip("Caps Lock is on",
|
||
|
|
"You might have made an error in your password\n"
|
||
|
|
"entry because Caps Lock is turned on.\n"
|
||
|
|
"\n"
|
||
|
|
"Press Caps Lock key to turn it off.");
|
||
|
|
tip.SetIcon(wxICON_WARNING);
|
||
|
|
tip.ShowFor(password);
|
||
|
|
@endcode
|
||
|
|
|
||
|
|
Currently this class has generic implementation that can be used with any
|
||
|
|
window and implements all the functionality but doesn't exactly match the
|
||
|
|
appearance of the native tooltips (even though it makes some efforts to
|
||
|
|
use the style most appropriate for the current platform) and a native MSW
|
||
|
|
version which can be only used with text controls and doesn't provide as
|
||
|
|
much in the way of customization. Because of this, it's inadvisable to
|
||
|
|
customize the tooltips unnecessarily as doing this turns off auto-detection
|
||
|
|
of the native style in the generic version and may prevent the native MSW
|
||
|
|
version from being used at all.
|
||
|
|
|
||
|
|
Notice that this class is not derived from wxWindow and hence doesn't
|
||
|
|
represent a window, even if its ShowFor() method does create one internally
|
||
|
|
to show the tooltip.
|
||
|
|
|
||
|
|
The images below show some examples of rich tooltips on different
|
||
|
|
platforms, with various customizations applied.
