Hi,

IIRC, setAttribute(Qt::WA_TranslucentBackground); is what you are looking for.

@SGaist i tried it but still same :(

I want to make transparent to default White background of button and lineedit .

@takoo

Can be made with a stylesheet and
"background: transparent"

[takoo]

@mrjj ``` still same :(
QLineEdit
{
background:transparent;
}

[mrjj]

Dont set directly on LineEdit
Set on its parent. (dialog/mainwind)
Then it works.
Or set as no Type
Try right click LineEdit, change stylesheet, and paste
background:transparent;
directly also works.

For some reason, i have yet to learn, setting
QLineEdit
{
background:transparent;
}
directly on Edit. Do not work. (for me).
Only via parent.

@mrjj NOT

[mrjj]

ok, u must override it from the other stylesheet then ?
Else i dont know.

Is that the sample ?
No changes, just run it?
If yes, then what platform you are on, might not support it or the
Qt version you are using is having a bug on that platform.

@mrjj i am using linux mint 17.3 and qt 5.5.1

[mrjj]

@takoo
ok. I have had issue on mint with xfce4.
Some stuff that worked in Kubuntu and windows did render differently on mint.
That was also 5.5.
Not sure if bug or what.

Could you test on other windows manager?

[takoo]

@mrjj ok i will test another window manager :) thanks for help

[mrjj]

@takoo
Super if possible.
I love mint + xfce4 but i did have some issues with rendering and dialogs
that fall behind parent.

So test transparent on other setup if u can and see if that is different :)

@mrjj it works for windows
