TGToolTip
A tooltip is a one line help text that is displayed in a window
when the cursor rests over a widget. For an example of usage see
the TGButton class.
TGToolTip(const TGWindow *p, const TGFrame *f, const char *text, Long_t delayms)
Create a tool tip. P is the tool tips parent window (normally
fClient->GetRoot(), f is the frame to which the tool tip is associated,
text is the tool tip one-liner and delayms is the delay in ms before
the tool tip is shown.
TGToolTip(const TGWindow *p, const TBox *box, const char *text, Long_t delayms)
Create a tool tip. P is the tool tips parent window (normally
fClient->GetRoot(), box is the area to which the tool tip is associated,
text is the tool tip one-liner and delayms is the delay in ms before
the tool tip is shown. When using this ctor with the box argument
you have to use Reset(const TVirtualPad *parent).
TGToolTip(const TBox *box, const char *text,Long_t delayms)
Create a tool tip in the parent window gClient->GetRoot(),
box is the area to which the tool tip is associated,
text is the tool tip one-liner and delayms is the delay in ms before
the tool tip is shown. When using this ctor with the box argument
you have to use Reset(const TVirtualPad *parent).
void Hide()
Hide tool tip window. Use this method to hide the tool tip in a client
class.
void Reset()
Reset tool tip popup delay timer. Use this method to activate tool tip
in a client class.
void Reset(const TVirtualPad *parent)
Reset tool tip popup delay timer. Use this method to activate tool tip
in a client class. Use this method for graphics objects drawn in a
TCanvas, also the tool tip must have been created with the ctor
taking the TBox as argument.
void SetText(const char *new_text)
Set new tool tip text.
void SetPosition(Int_t x, Int_t y)
Set popup position within specified frame (as specified in the ctor).
To get back default behaviour (in the middle just below the designated
frame) set position to -1,-1.
