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

[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

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?

@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

if i want to set radio buttons colors to different colors how to change the code?
(i want some green radiobuttons some red etc...)

[mrjj]

@rezaMSLM
the background-color controls that.
you can do
background-color: rgb(47, 255, 11);
to set a color using RGB

that controls all buttons color
i want some red, some green and so on

[mrjj]

@rezaMSLM
You can use names.
this is a MUST read.
https://doc.qt.io/Qt-5/stylesheet-syntax.html

QRadioButton#Name::indicator xxxxx

but i think the other leds you found will work better for this that style sheet. but
it should be doable.

[rezaMSLM]

i use this code:

void MainWindow::on_checkBox1_clicked(bool checked)
{
    if(checked == true)
    {
        ui->radioButton_2->show();
        QString StyleSheetOn("QRadioButton::mainwindow {width: 25px; height: 25px; border-radius: 7px;} QRadioButton#radioButton_2::indicator:unchecked { background-color: lime; border: 2px solid gray;}");
        setStyleSheet(StyleSheetOn);
    }
    else
    {
        ui->radioButton_2->hide();
    }
}

void MainWindow::on_checkBox2_clicked(bool checked)
{
    if(checked == true)
    {
        ui->radioButton->show();
        QString StyleSheetOn2("QRadioButton::mainwindow {width: 25px; height: 25px; border-radius: 7px;} QRadioButton#radioButton::indicator:unchecked { background-color: red; border: 2px solid gray;}");
        setStyleSheet(StyleSheetOn2);
    }
    else
    {
        ui->radioButton->hide();
    }


}

here is the result:

when showing one LED the other one is affected!

[mrjj]

@rezaMSLM
well i imagined you defined a big style sheet with
the names of all the LED
and set it once.
then hide() /show them

you can set stylesheet on mainwindow and it affects them also
no need to do directly on radiobutton.

[rezaMSLM]

@mrjj
I dont understand
please explain more

[mrjj]

@rezaMSLM
Ok
There is no need to set stylesheet on radio buttons.
If you right click main window and select Change stylesheet
you can put all lines there
QRadioButton#radioButton_2::xxx
QRadioButton#radioButton_3::xxx
QRadioButton#radioButton_4::xxx

for the colors u want.

all of it. for all names. and the default one.

then its always in effect.

and then just
ui->radioButton->show()/hide()

how many leds will there be ?

[rezaMSLM]

@mrjj
thanks alot

there will be 3 or 4 groups and about 10 to 15 LED's in each group

[mrjj]

@rezaMSLM
Ok, im a bit concerned about using names directly
ui->radioButton_2->show();
wont that become tons of names ?

[rezaMSLM]

@mrjj
yes it will
but i think this is the only way i can do

i'd like to use this LED indicator but dont know how put LED's in the coordinates i want to

LED example

[mrjj]

@rezaMSLM
well its possible to do more generic.
sender()) or lambda

its just a widget like radio button so its almost the same.
however, there is no designer version so you have to new it and place it.
(or use promotion as i did )

those leds will be fixed ?
So you have no need to save and load the locations?
