Text Effects

[BigEd]

Hi,

I am wanting to fade out the text on a QLabel to be transparent, then change the text, and fade back to black with the new text showing. The text is coming out of a data file so I can't create myself a movie in advance so I need to do it on the fly.

I can change it instantly but thought it might look better with an effect, since I had that thought I have regretted it ever since

I am currently using Qt3 and python and am stuggling to come up with a solution. I have read some bit about Qt4 and am wondering if it may be easier with that.

Any ideas would be welcomed.

Many Thanks in advance

Run a timer to change the text color. I think the approach would be pretty similar in both Qt 3 and Qt 4, just change the text color from the palette.

This is slightly complicated by the fact I have an image as the background on the window so whats behind the text label is not solid colour. So I need to fade to transparent somehow

QPalette palette = label->palette();
palette.setColor(QColorGroup::Text, QColor(qRgba(r, g, b, a))); // <-- 'a'
label->setPalette(palette);

QPalette palette = label->palette();
palette.setColor(QColorGroup::Text, QColor(qRgba(r, g, b, a))); // <-- 'a'
label->setPalette(palette);
