Do padding affect the tooltip ?

Pou Lin Chang

class A : public QLineEdit
{
public:
A()
{
setToolTip( "Some text here" );
setStyleSheet("padding-top: -2px;");
}
}

here when i hover my mouse on the QlineEdit, the tooltip text get cut off from bottom. But if i remove the padding the toolTip text displays it correctly.

So does applying padding or any stylesheet affects the tooltip ??? I read in other forum that it's Qt bug.

I would be glad if anyone can answer my queries. Thank you

Hi,

It's not a bug per-se. Your style sheet is basically interpreted as. "Every widget and child widget has a top padding of -2px". If you only want your line edit to have that padding then you have to use a more precise style sheet.

I get your point, but i am setting the stylesheet in the constructor of my class so wouldn't it be only for that class ?

It would be for that class and all its children.

Easy fix is to give class A object name and use that for style sheet
then only that is affected.

@mrjj i applied this setStyleSheet( " QLineEdit{ padding-top : -2 } " )

it worked. is it the right syntax ?

Yes its correct as it mean for all QLineEdits

if you just want for sure on a single one.
Give it a name (setObjectName(const QString & name))

and use
QPushButton#okButton { color: gray }

here button is called okButton

To add to @mrjj, if you don't set any scope to your style sheet, it will apply to everything from that widget to all its children.
