how to show LED in GUI and use push button to control it

[rezaMSLM]

hello
i want to load a map(or Image) in my gui and put some LEDs on it and use push button to control them.
how can i do this?

@rezaMSLM

You can have a look to QLedIndicator. It probably has teh functionality as you require.

[rezaMSLM]

to work with led i use this example:
https://github.com/melanholly/qt5-led-indicator-widget

but my first problem is how to load my image(the map) in GUI.
i have tried this way:
added a label to gui and choose pixmap in Qlabel menu and browsed to the image.(is this a good way?)
now my problem is that dont know how to put LED's on image in places that I want
can anyone help me?

@rezaMSLM
No its not a good way as its not an image :)
Its a widgets and you can either new a object and insert as website shows Or use
promotion to add it to form.
http://doc.qt.io/qt-5/designer-using-custom-widgets.html

So have the ledindicator.h / ledindicator.cpp in same folder as main project.
open mainwindow.ui
place a QWidget on the form
Right click the widget
choose promote
fill in the class name and .h filename
press Add
Then pres promote
run app

[rezaMSLM]

i put classname and .h filename "ledindicator" but error occured

Do you mean setting a background image for the MainWindow? If so, see example

yes thank you!

but the image is tile:

how to correct it?

i want something like this:

[MrShawn]

I made these with radio buttons.

I use setStyleSheet method and sent these strings:

/QString StyleSheetOn("QRadioButton::indicator {width: 15px; height: 15px; border-radius: 7px;} QRadioButton::indicator:unchecked { background-color: lime; border: 2px solid gray;}");
    QString StyleSheetOff("QRadioButton::indicator {width: 15px; height: 15px; border-radius: 7px;} QRadioButton::indicator:unchecked { background-color: black; border: 2px solid gray;}");

I dont set check i simply set style sheet, I suppose you could set stylesheets for checked and unchecked and use setChecked methods.

thanks
a good solution
but i have a problem!
when i put the radio button on a location on the map and run the program, thats fine but if i maximize the window, the map gets larger and so locations will move but radio buttons remain in previous locations. i want radiobuttons to move with map in order to remain on the location.
before window maximize:

After maximize:

EDIT:
i have used Qframe and set map as backgroundl to load the map in GUI

[mrjj]

@rezaMSLM
Make sure the radiobuttons are childs of the frame

thanks, worked!

another question:
i used this command to full screen the main window:
resize(QDesktopWidget().availableGeometry(this).size());

how to make the frame(map) the same size of the main window?

[jsulm]

@rezaMSLM If you use layouts then it should resize automatically

[rezaMSLM]

@jsulm said in how to show LED in GUI and use push button to control it:

@rezaMSLM If you use layouts then it should resize automatically

i use many radio buttons in different locations in the frame, if use layouts i can not put radio buttons any location that i want. in addition when resizing the main window the radio buttons move more than map locations and get moved to a wrong location.

[rezaMSLM]

the answer that solves my problem is that "how to set frame size to the size of main window without using layouts"

[rezaMSLM]

if i use layouts this happens:

you see that when resizing the window, the radio button is not attached to the map
