Detailed Description

Window class houses all widgets including other windows

Constructor & Destructor Documentation

◆ Window()

z::Window::Window	(	std::string	title,
		cv::Rect_< int >	r
	)

create a window with title and position and size of r.

Parameters

title	if window is the top window, this will be the window title. else if window is embedded inside another window, window will be framed and title will be the frame title. In case title == "", no frame will show.
r	window will occupy this rectangular space. If this window is not embedded inside other window x, y postions is not relevant.

Member Function Documentation

◆ close()

void z::Window::close ( )

close all windows

◆ draw_all_wrapped()

void z::Window::draw_all_wrapped ( )

draw all frames

◆ focus()

void z::Window::focus ( bool v )

virtual

also unfocus child widgets

Reimplemented from z::Widget.

◆ loop()

int z::Window::loop ( )

get keyboard event by calling cv::waitKey

◆ move_widget()

void z::Window::move_widget	(	z::Widget &	w,
		cv::Point2i	p
	)

move a widget that is already mounted. Just change the widget's xy position

◆ open()

int z::Window::open	(	int	flag = `cv::WINDOW_AUTOSIZE`,
		int	x = `-1`,
		int	y = `-1`
	)

Open another window. Call quit to close window that is opened.

Returns: return int value when quit is called.

◆ operator+()

z::Window & z::Window::operator+ ( z::Widget & w )

add widget to this window

◆ operator-()

z::Window & z::Window::operator- ( z::Widget & w )

remove widget from this window

◆ operator<<()

z::Window & z::Window::operator<< ( z::Widget & r )

copy to mat_

◆ operator>>()

z::Window & z::Window::operator>> ( z::Widget & r )

remove from mat_. sets hidden_ value to true.

◆ organize_accordingto_zindex()

void z::Window::organize_accordingto_zindex ( )

sort widgets according to zIndex_ and copy all widgets that is not hiddent to window matrix.

for mouse event

◆ popdown()

void z::Window::popdown ( int value )

close popup window.

Parameters

value this value will be handed over to function that is registered with popup function call.

◆ popup()

void z::Window::popup	(	z::Window &	w,
		std::function< void(int)>	f = `[](int){}`
	)

show popup window on window w, and register result function. popdown function will hand over int value to f.

◆ scroll_to()

void z::Window::scroll_to ( cv::Rect2i r )

use this to scroll or resize window.

◆ show()

void z::Window::show ( )

virtual

draw mat_

show window and its components

Reimplemented from z::Widget.

◆ start()

void z::Window::start ( int flag = cv::WINDOW_AUTOSIZE | cv::WINDOW_KEEPRATIO )

organize according to zindex -> set mouse callback -> show window

◆ tabs()

template<class... T>

void z::Window::tabs	(	int	xpos,
		int	ypos,
		T &...	wins
	)

inline

create a tab by combining multiple Womdows and will create tab navigation buttons on top

Parameters

xpos	x position to create tab.
ypos	y position to create tab. This is the Upper left postion of navigation button.

◆ tie() [1/2]

template<class... T>

auto z::Window::tie ( T &... checks )

inline

create a radio button by combining multiple CheckBoxes. RadioButton is a widget that allows one CheckBox to be selected at one time.

◆ tie() [2/2]

template<class T >

auto z::Window::tie	(	TextInput &	t,
		Button &	b1,
		Button &	b2,
		T	start,
		T	step
	)

inline

create a numeric spin button by tying a textinput and two buttons.

Parameters

start	number to begin with
step	step to increase or decrease when buttons are clicked.

◆ title()

string z::Window::title ( ) const

get title

◆ wrap()

template<class... T>

void z::Window::wrap	(	const char *	title,
		int	font,
		int	N,
		const T &...	widgets
	)

inline

@parma N margin.

Parameters

font	font height
