I want to update the text and symbol on legend items. I am creating legend text with symbol using series and CSeriesPointerItems. I thought of using OnGetLegendTextTchart event, but it is not getting fired. OnAfterDrawTchart event is getting fired. So I am unable to understanding why is it not happening?
Can you let me know what am I missing or how can we update the legend text and symbol?
There's an example showing how to use the Symbol OnDraw event to change the symbol on the legend. Find it at "All Features\Welcome !\Miscellaneous\Legend\Symbol OnDraw" in the Features Demo shipped with the installation.
There's another example showing how to use the Items property on the Legend to change the texts of the same. Find it at "All Features\Welcome !\Miscellaneous\Legend\Items property" in the Features Demo shipped with the installation.

I'm upgraded to Vaadin 23.3 Preview because of Tooltip component. Works and looks great. Only one question - I use the tooltip as a toggletip. I added an icon to my textfield and manually open tooltip by clicking it. In order to close the tooltip, I have to click the icon one more time. Is it possible somehow to close the tooltip by clicking the tooltip text also?
That's not supported, as the Tooltip feature is not intended to be used for anything interactive. As the docs say:
Tooltips only support plain text content. They aren’t focusable and
can’t contain interactive elements.
Due to technical (and especially accessibility) reasons, interactive popups like that need a different implementation. There are some vague plans to add such a feature to the Vaadin platform in the future, however.
One component in the Vaadin's Directory that can be considered better suited for the task is Popup.
I am using Tooltip for multiple input elements and showing the Tooltip on input elements both hovering and clicking. I need to prevent the JAWS reader from reading the Tooltip content while hovering. I have tried to remove the "role" attribute and set the "aria-hidden" attribute as true.
But none of this way works and the Tooltip still readable. Any assistance would be appreciable. we are using JAWS 2020.2008.24 ILM
There could be several things at play here. The first is that JAWS, by default, does not announce anything when you move the mouse so I'm puzzled why you are hearing something read when you hover. There's a "mouse echo" setting in the JAWS Setting Center but that's off by default for JAWS (unless you're running ZoomText). Did you specifically turn that feature on?
Secondly, you say you are showing the tooltip. So you're not relying on the default tooltip feature of browsers via the title attribute? You are handling the tooltip yourself and displaying it via javascript? JAWS will not announce newly displayed text unless the new text is in an aria-live region. Are you using live regions?
And lastly, if a tooltip attribute is being used, such as the title attribute, then the tooltip text might be used in the accessible name calculation or in the accessible description. It's the last attribute looked at (step 2.I). If it's being used in that manner, then you would not want to turn that off. It's expected behavior by JAWS users.
You may want to post some code to clarify all these issues in order to get a more accurate answer.
Requirements:
We have a text in Delphi RAD Studio editor and this text has been selected as a search result.
What happens
On any change (Del button or typing some text) changes are applied to the right of selection.
Expected
On any change (Del button or typing some text) the selected block is deleted and then the changes are applied.
Question
How?
The behaviour that you describe is simply how the IDE's search functionality is intended to work. You are expecting that when you search for text, the IDE will select occurrences of that text. However, it instead highlights occurrences.
There is no way (to the best of my knowledge) to alter this behaviour, short of writing an IDE plugin to implement your own search functionality.
To resolve this, use Ctrl + R.
I have the example code in my Angular.Dart component:
<paper-input bind-value="value" label="MyLabel" floatingLabel></paper-input>
The paper input shows the value that is in my Angular.Dart component, but the floatingLabel does not appear. However, upon clicking the input, the label appears with the standard animation as if it was hidden. It seems as though this is a bug with the "constructor" of the paper-input element. I expected the floating label to appear above the input field when text is in the input field regardless if it was newly created or not. Is there a way to fix this glitch?
Progress: (github.com/Polymer/paper-input/issues/117)
I am looking intensively at the issue listed above, however implementing the fix accordingly is not as easy. As suggested by #GünterZöchbauer, I can use the dart:js library. However it appears that the solution was designed specifically for PolymerJs and not particularly for PolymerDart. Maybe I am overthinking things, but I am unable to perform a simple port.
But the issue does bring up a good point. The element is unable to detect the change (for what ever reason). So something needs to poke it to trigger an update. I currently have the dart context to the Element, however the class (paper-input is the class) does not contain the method inputAction upon inspection with WebStorm. However assuming that the inputAction method was firing an event, I can simply use the dispatchEvent method. However which event will trigger the event without modifying the object itself? And not crashing the browser would be great (I have been crashing the webpage with Chrome's Aw, snap! blue screen of death with some event tests).
Is there a setting for highcharts tooltips where you can set it to display on click versus hover?
I have seen a lot of people discussing the tooltip staying on click but then there is still the hover present. Is there a way to disable the hover and use only click?
There is not a setting for that in Highcharts currently.
There is a feature request for this functionality here: http://highcharts.uservoice.com/forums/55896-general/suggestions/2607304-allow-the-tooltip-to-appear-when-a-point-is-clicke
Feel free to add your votes and comments.
UPDATE:
I have started using the jquery UI dialog for this purpose.
I disable the tooltip in Highcharts, and add a click event to the point in the plotOptions.
In that click function I call an external function, sending it the point object, and build my tooltip within the dialog.

You could also use Highslide for this purpose, and keep it all in the family.

Adding for those who has problems like me with useHTML: true and wants to display tooltip only on click and not on hover and wants to have only one tooltip on screen.
Here is a fiddle.
