Issue with Animating Progress Bar?

Omni_Philm

Hello all,

I have this issue where the animation of the progress bar does not complete.

I am animating the movement of the progress bar when the value changes.

For example, I animate the value change from 0 to 25. In actuality, the bar moves from 0 to 20%. Then, when a repaint occurs, the value jumps up to the desired 25%.

Has anyone else ran into this issue?

Setting up the progress bar:

ui->progressBar->setTextVisible(false);
ui->progressBar->setRange(0, 100);
 p_ProgressBar1Animation = new QPropertyAnimation(ui->progressBar, "value");

Code that is ran in order to animate the value:

void MainWindowController::changeProgressBar_1Value(int value)
{
    int someValue = 0;

    if(value == 0)
        someValue = 0;
    else if(value < MIN_PROGRESS_BAR_VALUE)
        someValue = MIN_PROGRESS_BAR_VALUE;
    else
        someValue = value;

    p_ProgressBar1Animation->setDuration(PROGRESS_BAR_ANIMATION_DURATION_MS);
    p_ProgressBar1Animation->setStartValue(ui->progressBar->value());
    p_ProgressBar1Animation->setEndValue(someValue);
    p_ProgressBar1Animation->start();
}

Hi,

Did you modify the easing curve of your QPropertyAnimation ?

@SGaist
The easing curve? I am going to go with no on that since I am not sure what that is. But who knows, maybe I ended up editing it without realizing it. Where do I go to check that value?

Yeah so I am playing around with the easing function and the "bug" is not going away
