I am using jqvmap to render clickable world map. I set borderWidth=0 but still it is giving border to each country. I want all maps with no border. Seems like I will need to set some other property along with borderWidth.
If no possible then how I can set map fill color to border for selected countries so it will look like no border.
Please help.
By simply setting the BorderColor parameter to the same color as the map I was able to make them "disappear". Looking at the jquery.vmap.js I see that there is a condition such that the parameter passed along with the map for setting the border width will only be used if it's greater than 0, so you can either a) set the border to the same color as the map or b) modify the jquery.vmap.js to set the border to 0 as a default. I've tried both and got the desired result.

Is there a way to detect the background color at one certain point of the page dynamically? I have a website with a fixed header, and the default logo on it is white (default background is black). However, as I scroll down there are sections that have white background, so the logo would have to change colour to black.
Setting it based on scrolling position is not possible, because all sections have different heights and the height is often dependent on the content.
I have found mix-blend-color, but unfortunately its support is pretty bad across browsers. Also tried numerous npm packages, but none of them seem to pick up the background colour.
Is there another way to dynamically change the logo color without getting the background color?

I never tried this, but I think this might lead to the answer.
You can use document.elementFromPoint.
This will retrieve the top element at some (x, y) point.
So you can set the x and y to 1px down the border of your modal ( or some place where you know that will only have element with the background color you want) and get the element.
And check, on a scroll event listener, what is the element at that position and get it's background color.
Is this a good thing to do? Maybe not, but it works and it have good support across browsers.

Setting it based on scrolling position is not possible
Of course it's possible!
If your modal is with position absolute, what you can do is get the modal's ref and use element.getBoundingClientRect() to get it's position.
Then on each section, you also get the ref (you will have an array of section's ref) in the parent component, which knows the modal's refs and section's ref.
Then, on a scroll event, you use getBoundingClientRect on each section element and check if it's inside the modal logo.
To check if it's inside, you can simply use the top and bottom ( if the scroll is vertical).
This is harder to implement, but I think it's the way to go.
I want to apply RoundBorder style to MultiButton Line2 label when horizontal layout is set to true but calling mb.setHorizontalLayout(true); but I can't because LineX labels are not accessible outside the MultiButton.
I know that I can create curved border using theme designer and applying the uiid to the label using any of the setUIIDLineX() method but I don't want to use it because it didn't give me what I want in some device pixel density.
Is there any other way to style MultiButton internal components(Labels) through code?
Again, why is it that LineX labels are not exposed like icon label?
Exposing the LineX labels will equally enable developers to set icons for the individual labels depending on what the developer want to accomplish.
Thanks.
No one asked for that so we didn't add such getters. You can file an RFE for that or submit a pull request which will probably be quicker.
Notice you can style the round border in the current version of the designer so you can use a the UIID's to set the round border too.
I am using jfree-chart library to create line chart.
I want to know how to set background color of item-label in line-chart.
Item labels don't even have background color, just text. You could try one of the org.jfree.chart.annotations like XYTextAnnotation, which has a setBackgroundPaint() method.
What is the name of the element of a text box control which I need to manipulate to achieve a change of the color of the position marker in the text box?
The normal foreground attribute changes the actual texts color, but the position marker stays the same color.
To modify the color of the caret (which assume is what you call "positionmarker") you have to set the CaretBrush property of the TextBox.
I am getting the following "margin" around my menuitems that i cannot figure out how to remove:
I have tried setting the margin to 0 and adjusting the border brush color, nothing seems to work.
I am just looking to either change the color to match the background or remove it completely.
Thanks
You probably need to change the Template of the MenuItem as that part might not be configurable via properties. (-How to get the default template-, so you can modify it)
