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

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:
alt text

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

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.

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

@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

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:

alt text

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?

rezaMSLM

@mrjj
yes LED's are Fixed

mrjj

@rezaMSLM
ok so it will work pretty fine just placing them in designer.

in the sample
https://www.dropbox.com/s/qi7frrlyvnrjvy6/LedTest.zip?dl=0

i use promotion. that allows you to copy them around and at run time they be the leds.

did u try sample?

did u try sample?

yes
but dont know how to put LED's on the places i want on map

mrjj

@rezaMSLM
you just copy the widget and place it where u want ?
alt text
the widget is the led. so it work the same as radio buttons.

rezaMSLM

@mrjj
I still don't understand how to put LED's on different places on the map

please explain more.
how to use promotion?

mrjj

@rezaMSLM
you put a widget on the form and right click it
select Promote
then give it the class name and include
alt text
Then click Add
and then promote.
When run, its now a Led.
you must have ledIndicator.cpp and .h added to project
