Description

Hello,

I'm using wt 3.3.1 and I'll show and hide a widget with animation.

So I used the following code for show:

this~~_infoBox~~>setHidden(false, WAnimation(WAnimation::Fade, WAnimation::Ease, 1000));

It works as expected.

For hiding I used this line:

this~~_infoBox~~>setHidden(true, WAnimation(WAnimation::Fade, WAnimation::Ease, 500));

But after it, the widget isn't hidden. So I tested other lines. First:

this~~_infoBox~~>setHidden(true);

It works! But the following don't work:

this~~_infoBox~~>setHidden(true, WAnimation(WAnimation::Fade));

Greetings

Torsten

Hi Torsten,

I tried to reproduce this on hello world, fading a WLineEdit, but it seems like animation works as expected. Can you make a small example that demonstrates the problem?

BR,

Wim.

Hello Wim,

sorry for my late answer, I hadn't an account before.

That's what I had done:

Aplication constructor:

enableUpdates(true);

class ChannelControlPanel : public MyPanel {
public:
    ChannelControlPanel();
private:
...
    WContainerWidget *_infoBox;
    WTimer *_changeMessageTimer;

void ChannelControlPanel::_changeMessage()
{
    if (this->_messagesQueue.size() > 0) {
        this->_infoBox->clear();
        this->_infoBox->addWidget(new WText(WString::tr(this->_messagesQueue.front().toUTF8())));
        this->_messagesQueue.pop_front();
        if (this->_infoBox->isHidden()) {
            this->_infoBox->setHidden(false, WAnimation(WAnimation::Fade, WAnimation::Ease, 1000));
            this->_infoBox->clicked().connect(this, &ChannelControlPanel::_changeMessage);
        }
        if (this->_changeMessageTimer == NULL) {
            this->_changeMessageTimer = new WTimer(this);
            this->_changeMessageTimer->setInterval(7500);
            this->_changeMessageTimer->timeout().connect(this, &ChannelControlPanel::_changeMessage);
            this->_changeMessageTimer->start();
        }
    }
    else if (this->_infoBox->isHidden() == false){
        this->_infoBox->setHidden(true, WAnimation(WAnimation::Fade, WAnimation::Ease, 500));
        this->_changeMessageTimer = NULL;
    }
}

And the part thats wondering is:

setHidden(false, ...);

and

setHidden(true);

works as expected, but

setHidden(true, WAnimation(...));

don't works.

I've a new information. It isn't working for only with chrome (I'm testing with chrome 35). At Firefox its ok.

I have experienced a similar problem (also posted this on the forum).

The below full example exhibits the problem in Firefox 30 and Chromium 35. The hide_me_widget stays where it was until I reload the page. After reload, it is immediately gone.

#include <Wt/WApplication>
#include <Wt/WPushButton>
#include <Wt/WContainerWidget>

Wt::WAnimation slide_in_from_left(Wt::WAnimation::SlideInFromLeft);

class FooApplication : public Wt::WApplication {
public:
    FooApplication(Wt::WEnvironment const& env)
        : Wt::WApplication(env),
          hide_me_widget(new Wt::WContainerWidget(root())),
          hider_button(new Wt::WPushButton("hide!", root())) {

        hider_button->clicked().connect([&](Wt::WMouseEvent const&) {
            hide_me_widget->animateHide(slide_in_from_left);
        });
        hide_me_widget->addWidget(new Wt::WText("I can be hidden."));
    }

    static FooApplication* create(Wt::WEnvironment const& env) {
        return new FooApplication(env);
    }

private:
    Wt::WContainerWidget* hide_me_widget;
    Wt::WPushButton* hider_button;
};

int main(int argc, char** argv) {
    return Wt::WRun(argc, argv, &FooApplication::create);
}

Hey,

I could fix the issue from Marcel but I guess that's unrelated to the original problem.

I believe there must be something we are overlooking in the animation that is caused by how you are setting up the widgets. Can you isolate the misbehavior in a self-contained test-case?

Hello,

sorry for the late answer. I'll try to make it in the next days, but I was too busy (by other important implementations) to do it.

Regards,

Torsten

Hello,

I created an example app. There you can see the not working animation on hiding.
