How do I have the chart display without any engagement buttons clicked on?
Would like the top button (see picture), which is currently defaulting on, to default off.
Currently Holoviews does not expose this option directly, so you have to define a custom hook which modifies the underlying bokeh model, it should look something like this:
def tools(plot, element):
plot.handles['plot'].toolbar.active_drag = None
hv.Curve([]).opts(hooks=[tools])

I'm trying to make a line graph change color on mouse click by using the select.lineStyle.color attribute.
I'm able to trigger a colour change for the points upon mouse click using select.itemStyle.color and I'm expecting the select.lineStyle.color attribute to change the color of the graph but , it doesn't seem to work despite the documentation saying that select should work for all series.
I even programmatically fired the "select" event (not in the sandbox) but no changes were observed in my line graph.
My code sandbox
Extract from the docs
In addition, we've added click to select to all series, an interaction that was previously only available in a few series such as pie charts and maps, allowing developers to set it to single or multiple selection mode, and to listen to the selectchanged event to get all the selected shapes for further processing. As with emphasis and blur, the selection style can also be configured in select.
Please help me. I've been working on this for a week and found no solutions here. Is there something I'm missing?
Got my answer directly via posting an issue on their Github page.
Apparently, select is only applicable for data object, not series objects(or whatever you call it). So this feature is not available.
What I did, like most people, is to listen to the mouseclick event and update the series-line.lineStyle.opacity property in options directly to blur out other lines. Set triggerLineEvent:true so that clicking any part of the line will fire the mouseclick event, instead of just the data points.
Using Mapbox-gl-draw (https://github.com/mapbox/mapbox-gl-draw)
I am able to get the basic example up and running, and this package does everything I need. However, I am having trouble figuring out how to activate the draw functionality programatically. For example, my application has some panel overlays, and as part of a form I'd like to activate the draw ability by clicking a custom button, not the control button that shows on the map. Ideally I'd like to keep the map control button hidden (which I can do).
I've scoured the documentation with no luck. Anyone have any insight?
Demo of the functionality I am referring to here: https://www.mapbox.com/mapbox-gl-js/example/mapbox-gl-draw/
It's documented in the API reference
changeMode(mode: string, options?: Object): draw
Changes Draw to another mode. Returns the draw instance for chaining.
How may I force a redraw of All Vaadin charts in a dashboard to toggle dataLabels on or off?
I would like to allow my app user to add/remove chart dataLabels for All charts on their dashboard; forcing a redraw similar to when changing themes say from VaadinTheme to GridTheme.
How may I achieve this?
How does changing themes work under the hood, what is the source code that does this?
e.g.;
I know I could redraw a single chart individually by resetting its plot options and then redrawing it:
.
.
.
PlotOptionsColumnRange columnRange = new PlotOptionsColumnRange();
columnRange.setDataLabels(new Labels(true));
columnRange.setDataLabels.setFormatter(/* some javascript about this.y */);
conf.setPlotOptions(columnRange);
chart.drawChart(conf);
But I want to do it for All charts on a dashboard; like having a Listener that does
ChartOptions.get().setTheme(new VaadinTheme())
then
ChartOptions.get().setTheme(new GridTheme())
and viceversa
Maybe I can reset the plotOption dataLabels then reset the theme to force a redraw with the new dataLabel state?
Please advise...
p.s.
I don't want to make changes to my user saved data in my database, i.e., I don't want this label toggle to be persistent. I want to toggle dataLabels just like a toggling themes.
Please look at:
http://demo.vaadin.com/charts/#ColumnRange
to see what I mean.
Ok, two solutions:
A coworker of mine that worked on the Dashboards helped me with the first answer to this question.
Basically, you have to clear all charts, then iterate through ea. chart in a particular dashboard (stored in the DB), and rebuild ea. chart w/ your decision to have or not have a dataLabel, placing it back in that dashboard; but I wanted to avoid this as it might take a performance hit.
Also I later got a response from Pekka of the Vadding team, as follows:
'You can easily hide the dataLabels with basic css. For example, if you can apply a stylename "dataLabelsHidden" to you UI, then you could write in your stylesheet a specific enough rule for hiding the labels. I quickly tested the demo with this:
.v-ui.dataLabelsHidden g.highcharts-data-labels {
display: none;
}
This way you won't have to update all your charts when the labels on/off is triggered.'
The JavaFX 2 colour picker has a button that pops up a colour chooser pane like so:
I'd like to do something similar, in that I'd like a custom pane to pop up when the button is clicked on and disappear when something else is clicked (in my case, a few image thumbnails). What would be the best way of achieving this? Should I use a ContextMenu and add a pane to a MenuItem somehow, or is there something else I should look at?
It's kind of difficult to do well with the current JavaFX 2.2 API.
Here are some options.
Use a MenuButton with a graphic set in it's MenuItem
This is the approach taken in Button with popup showed below's executable sample code.
Use a PopupControl
Take a look at how the ColorPicker does this in it's code.
ColorPicker extends PopupControl. You could do this, but not all of the API required to build your own PopupControl is currently public. So, for JavaFX 2.2, you would have to rely on internal com.sun classes which are deprecated and will be replaced by public javafx.scene.control classes in JDK8.
Use a ContextMenu
So, I think your idea to "use a ContextMenu and add a pane to a MenuItem" is probably the best approach for now. You should be able to do this by using a CustomMenuItem or setting a graphic on a normal MenuItem. The ContextMenu has nice relative positioning logic. A ContextMenu can also be triggered by a MenuButton.
Use a Custom Dialog
To do this, display a transparent stage at a location relative to the node.
There is some sample code to get you started which I have temporarily linked here.
The sample code does relative positioning to the sides of the main window, but you could update it to perform positioning relative to the sides of a given node (like the ContextMenu's show method).
Use a Glass Pane
To do this, create a StackPane as your root of your main window. Place your main content pane as the first node in the StackPane and then create a Group as the second node in the stackpane, so that it will layer over the top of the main content. Normally, the top group contains nothing, but when you want to show your popup, place it in the top group and translate it to a location relative to the appropriate node in your main content.
You could look at how the anchor nodes in this demo are used to see how this might be adaptable to your context.
Is there a relevant update for this for JavaFX8?
There is not much difference of relevance for Java 8, in general the options are as outlined in this post based on Java 2.2 functionality. Java 8 does add Dialog and Alert functionality, but those are more targeted at use of dialogs with borders, titles and buttons rather than the kind of functionality desired in the question. Perhaps you might be able to start from the Dialog class and heavily customize it to get something close to what is needed, but you are probably better off starting from a blank stage or PopupControl instead.
I'm using tiny mce in one of my projects and client do not want to use the Horizontal tool bar of tiny mce. He wants a centralized custom tool bar from where user can control all the properties like text color, type of text, size, back grounds and every thing that is needed to do while designing a web page using templates. I configured the mce instance with out its default tool bar and controlled the properties from the customized tool bar. And the properties are applied to the tiny mce instance as a whole. But now, the requirement has come up that, the text editing should be in MS office style.That means, if user has placed cursor at one place and changes color, nothing will be affected, but if he starts typing from the cursor position the text should have the color which was set recently. I tried to use the external tool bar option. But, my work area and customized tool bar are at different z index levels. So, positioning the tool bar fails. If I append the tool bar to my customized tool bar, it is not click-able. So, how to invoke tiny mce's core functionality using customized tool bar?
Or, Kindly suggest, should I change editor ? Then, which one should I go for ?
EDIT
As per the suggestion, I'm writing the function save the property styles and insert the span at caret position. But I'm facing some problems and could not do it after spending whole day. I could add span at caret position by using following code.
marker = ed.selection.getBookmark();
ed.selection.moveToBookmark(marker);
tinyMCE.execCommand('mceInsertContent',false,'<span id="mytitle"></span>');
But still, I failed to type inside the new span. Also, I could not figure out how to set styles to this span.
If your aim is to have your tinymce behave like MS Office you should write an own plugin which will take care of this.
I suggest if a user has placed the cursor at one place and changes color you save this color as a setting to your tinymce instance like: ed.color = 'choosencolor';
When the user start typing now you can insert a span on the first keystroke and set the color as css class or style property to this span.
