Constructor & Destructor Documentation

TGToolTip() [1/5]

TGToolTip::TGToolTip ( const TGToolTip &  )

privatedelete

TGToolTip() [2/5]

TGToolTip::TGToolTip	(	const TGWindow *	p = nullptr,
		const TGFrame *	f = nullptr,
		const char *	text = nullptr,
		Long_t	delayms = 350
	)

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.

Definition at line 81 of file TGToolTip.cxx.

TGToolTip() [3/5]

TGToolTip::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).

Definition at line 116 of file TGToolTip.cxx.

TGToolTip() [4/5]

TGToolTip::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).

Definition at line 150 of file TGToolTip.cxx.

TGToolTip() [5/5]

TGToolTip::TGToolTip	(	Int_t	x,
		Int_t	y,
		const char *	text,
		Long_t	delayms
	)

Create a tool tip on global coordinates x, y.

text is the tool tip one-liner and delayms is the delay in ms before the tool tip is shown.

Definition at line 181 of file TGToolTip.cxx.

~TGToolTip()

TGToolTip::~TGToolTip ( )

virtual

Delete a tool tip object.

Definition at line 212 of file TGToolTip.cxx.

Member Function Documentation

DrawBorder()

void TGToolTip::DrawBorder ( )

virtual

Draw border of tool tip window.

Reimplemented from TGFrame.

Definition at line 222 of file TGToolTip.cxx.

GetText()

const TGString * TGToolTip::GetText

(

)

const

Get the tool tip text.

Definition at line 430 of file TGToolTip.cxx.

HandleTimer()

Bool_t TGToolTip::HandleTimer ( TTimer *  t )

virtual

If tool tip delay timer times out show tool tip window.

Reimplemented from TGWindow.

Definition at line 288 of file TGToolTip.cxx.

Hide()

void TGToolTip::Hide

(

)

Hide tool tip window.

Use this method to hide the tool tip in a client class.

Definition at line 250 of file TGToolTip.cxx.

operator=()

TGToolTip & TGToolTip::operator= ( const TGToolTip &  )

privatedelete

Reset() [1/2]

void TGToolTip::Reset

(

)

Reset tool tip popup delay timer.

Use this method to activate tool tip in a client class.

Definition at line 263 of file TGToolTip.cxx.

Reset() [2/2]

void TGToolTip::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.

Definition at line 277 of file TGToolTip.cxx.

SetDelay()

void TGToolTip::SetDelay

(

Long_t

delayms

)

Set delay in milliseconds.

Definition at line 399 of file TGToolTip.cxx.

SetPosition()

void TGToolTip::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.

Definition at line 409 of file TGToolTip.cxx.

SetText()

void TGToolTip::SetText

(

const char *

new_text

)

Set new tool tip text.

Definition at line 390 of file TGToolTip.cxx.

Show()

void TGToolTip::Show	(	Int_t	x,
		Int_t	y
	)

Show tool tip window.

Definition at line 233 of file TGToolTip.cxx.
