Modifying custom style, derived from QPlastiqueStyle to prevent rollover highlighting

Hello,

I am developing a Qt for embedded Linux application to be used with a touchscreen. I'm using a custom style, derived from QPlastiqueStyle but with "chunky" scrollbars to ease use with a touchscreen.

It is inappropriate how QPlastiqueStyle has a rollover effect, given that this application will only ever be used with a touchscreen.

Is there a way to prevent the rollover highlight effect from appearing?

Thanks,

which element's rollover event are you talking about..whichever element it is..u can disable it by using "hover" property in stylesheets.

I am referring to QPushButton's "hover" events....when they take on blue highlights while the mouse cursor is rolled over. That's all I want to change.

I'm already using a custom style. Can I further extend it to suppress this hover behaviour?

try:

Code:

---

urPushButton->setAttribute(Qt::WA_Hover, false);

---

talk2amulya,

Hmm....I appreciate the suggestion, but that will create a lot of boiler plate that will have to be maintained for dozens of QPushButtons. I was hoping to achieve the same end by modifying my application's custom, QPlastiqueStyle derived style.

I realised that I could do what you've suggested for all widgets in my style:

Code:

---

void QMyStyle::polish(QWidget* widget) // re-implement virtual function from QStyle
{
    widget->setAttribute(Qt::WA_Hover, false);
}

---

This works; the rollover effect disappears. However, I now have another problem: When I actually press a button, the blue highlighting "sticks" to it until it is re-drawn.

I have no idea why this might be. Do you?

maybe you have done certain stuff with QStyle::State_Sunken, if not, u can work on drawPrimitive() for your button and resolve the issue
