Dynamic Input to MarqueePane

[dinsacet]

Hi, everybody

Is it possible to update the MarqueePane running Text dynamically? If possible pls help me how to do that.

Thanks,

Please invoke MarqueePane#startAutoScrolling() after you reset the parameters.

Thanks,

Hi,

Thank you very much. I have identified the problem. I have already set startAutoScrolling option when I reset the parameter. But the reset parameter is smaller than the Marquee Pane size, that’s why the text is not running.

I have one more doubt; my requirement in Marquee is for Trading Application

1.) Dynamically update the Marquee running text with the specified field only. While update, the running text is not restarted. Instead it will update only the specified field.

For example,
Symbol – TCS, Last night price – 1000, Current price – 1002
Symbol – Infosys, Last night price – 2000, Current price - 1999

I will display the List of Information (symbol, price) in the Marquee Pane. Price gets updated frequently.

While price updates, we don’t want restart the running text, only that value updated is enough. Could you please guide me?

Regards,
Dinesh Kumar K.

Please try just update your List and it should be able to be updated in the MarqueePane. I tried in our MarqueePaneDemo and it works.

Thanks,

Hi,

Can i get the sample program for the above scenario ? It would be more helpful for me.

Thanks,

Please try the following code. We update the text in StyledLabel while clicking the button "Update text" then you'll see it gets changed in UI. Please try do the same thing to your list. Just make sure you invoke yourList#repaint() to update the UI if necessary.

Code: Select all
