QCombobox dropdown list transparent QComboBoxPrivateContainer

[minjunkim]

Hi,

I want to apply transparency to the qcombobox drop down list.

below is my Combobox

I found out that I can't solve with a stylesheet.

I also found some ideas for QComboBoxPrivateContainer

below is this.

if (combo->view()->parentWidget())
combo->view()->parentWidget()->setWindowOpacity(0.5);

but it didn't work.

is there some ideas?

Hi,

What version of Qt are you using ?
On what OS ?

You likely have to create a proxy style, for example the QMacStyle class sets the opacity.
