I am attempting to create an indicator which will have the background colors only wrapping the candles, leaving the rest of the chart white or black.
I am unable to find functionality for this. Is it possible even with the v4 update?
Thanks all,

I'm using svg as a background image (logo) in a WP menu plugin and i want it to change a color (fill) when hovered. As it's a free version of the plugin i can't use image, object etc - i have to use my svg as a background image. I've to support IE (9+) so masks/filters are out of question and i'm pretty much left with svg-sprites. That's okey, i know how to do it (using use/xlink:href).
But now comes a tricky part. I want my svg to change only fills of some groups/paths while hovered leaving others untouched. I can only change colors of all paths/groups together in a background image with svg-sprites afaik. Is there a way to do it? Thank you in advance!
I’m using PyQt4/PySide, but this problem occurs in both, so I think it’s a Qt problem generally. I have a TableView. When I want to set the background color of highlighted table items in Windows, I can get the TableView’s palette and call
palette.setColor(QPalette.Highlight, QColor(someColor))
and that sets the background color of a highlighted item, no problem. However, this does not work in Linux. (Specifically the different versions of Ubuntu that I’ve tried.) Instead the highlighted color is always an orange color that Ubuntu likes to use. Is there a way to fix this? Setting other types of colors, such as QPalette.Text, works fine, it’s a QPalette.Highlight issue only.
I want to show a ProgressBar. I am using this code:
EditorGUI.ProgressBar(Rect(3,45,100-6,20),20/700.0, "Armor");
I want to change the color of the ProgressBar from a light blue color to a red color. How can I do this?
As it stands, it doesn't appear that you can. However, I had a similar issue where I wanted a very customized bar with different colors to denote different things. I ended up using EditorGUI.DrawPreviewTexture. If you initialize the colors you want to use as a Texture2D, then pass them into that function with the properly placed rectangles, you can create portions of a bar that can change size and location to give the appearance of a standalone progress bar, especially if you keep the positions and size updated in the Update() function.
I am using the google maps and place around 800 markers from a db...
Now I have several question for the fine tuning of that map...
http://camodesign.de/stickermap/geomap.php
I am using a styled map - now I'd like to apply a button to hide/show the labels for streets etc... but when I set a style via "map.setOptions({styles: MyStylesArrayShowLabel});" that kills all my markers that have a already been placed. Is there a way to set the style on the fly without destroying the markers?
I have set a background for the map via "mapOptions" to avoid those ugly grey tiles. Is there a way to do this for the streetview pano too?
I had set a full screen panorama of 100% width and height but the streetview seems only
to use 60% even when the rest of the screen show grey. Here I don't really have a clue - is it a bug just on my browser?
(+) was trying to use the info bubble instead of the info window for more style
possibilities but the script was hanging and working too long.. after minutes it put out the result correct... seems the bubble had some problems on massive marker use?
had any one similar experiences with it?
Glad for any other suggestions?
(all markers [excluded the home marker/infowindow] are generated from a db via SQL and PHP)
I have been doing some searching the last couple of days and I have been curious how to do this. I have a UIImagePickerController.
So I want to add a effect like black and white, sepia, etc. I am creating a custom UIImagePickerVController and I am curious. Can this be done with OpenGL ES? If so, how?
This is possible through the use of pixel shaders using OpenGL-ES 2.0. You could also write an Objective-c++ routine that gets all the pixels of your image into an array then applies a custom algorithm to modify the color of the image.
