I'm using JavaFX in Eclipse from JDK 1.8.0_72. I want to display an image in the background of a scroll pane. I'm using the following code to do this:
ScrollPane s2 = new ScrollPane();
s2.setContent(label);
s2.setStyle("-fx-background-image: url('DungeonRoomImage.png');");
This works just fine on other objects such as Labels and GridPanes but for some reason not on scroll panes where it's displaying a grey block in the middle covering up the image. If you look closely between the border and grey center you can see the image peeking out.

The same issue occurs when changing the background color of a scroll pane, but is solved by using
-fx-background:
instead of:
-fx-background-color:
I've tried using setBackground but that renders the same result
s2.setBackground(new Background(new BackgroundImage(new Image("DungeonRoomImage.png"), null, null, null, null)));
Could anyone suggest a way to get rid of the grey background or a way to work around the issue?
Here's how the background image should look

Set the background image on the scroll pane's viewport. Using an external CSS file:
.scroll-pane .viewport {
-fx-background-image: url('DungeonRoomImage.png');
}

I am developing a RCP4 application, where I used toolbar. In some system toolbar and part label are same alignment. But some system toolbar is coming another line of part tab. Why this kind of things are happening?
It looks like this is because the height of the icons in the tool bar are bigger than the calculated height of the part tab area. This causes CTabFolder to move them to the next line.
You can set the height of a CTabFolder in the CSS using swt-tab-height. For the part stack folder this may work:
.MPartStack
{
swt-tab-height: 22px;
}
I began to work with Unity3D since one month and I'm trying to do an application which contains a menu, composed by a panel and several buttons. At this moment, I'm trying to customize the menu, I change the fill color of the panel and buttons, but until now I could not change the border color of the buttons. There is any way to customize the border's color of the UI buttons? I would appreciate your help. :)
The easiest way to add an outline to your button is to use the Outline component (doc).
Simply add the Outline component where your button image or text is. Then configure it how you like it :)
The above results in the following button:
No, you can not change just border color. If you use default buttons, take a look at Source image. It is basically a grey square with black borders. So when you change color of image black color remains black.
To customize buttons as you want you need either create nested UI elements:
or create sprites with colors you want and replace source image
I find nested UI elements to be the easiest way to do something like this. Simple example:
Start out by creating a panel and change the scale until you get the desired size for your button. This will be your "borders".
Next create another panel as a child of the panel you just made and change the scale to be just slightly smaller than your first panel and change the color.
In the Inspector for your panel, add component and type in Button and add it as a component.
Finally, add a text as a child of your panel for a label and you're done.
I have made a project previously where I set a UIButton to have both text and also an image (in interface builder).
I have created another project and I want to achieve the same thing, but when I set the button to have an image, the title disappears (it's not getting hidden behind the image).
I can't seem to figure out why this is so if anyone could shed some light on this subject I'd appreciate it!
Thanks.
Change your button to custom type. put the image on then put the text in.
You will need to put your own background on it, but at that point you will be able to use the edge settings to position both the text and the image.
Every button that I have with image and text is set to custom and ultimately has its own bg image as well.
Oh, another thing I use. Is the cornerRadius. To give the view the rounded effect like the buttons have by default.
saveButton.layer.cornerRadius = roundingNumber.floatValue;
Additionally you should be able to use the borderWidth and borderColor in conjunction with cornerRadius to get a button that looks quite similar to the original button
saveButton.layer.borderRadius = 1.0f;
saveButton.layer.borderColor = [[UIColor blueColor] CGColor];
// These are not the exact values (or maybe they are) but you get the idea.
hope that helps.
Correction
After Spending a little time investigating, it appears that when you put an image in the button. the text is shoved off to the right.
Use the edge settings to bring it back over the image.
With the button selected, Look in "Attributes Inspector" > Button > Edge > (Dropdown "Title")
the equasion I have come up with is
[Edge inset for Title] Left = -(imageWidth * 2)
This should Left align your title with the image that you have put in.
Custom positioning will need to be done to make it look correct.
This can be done entirely in the Interface Builder and you can use RoundedRect button style
Here are some images demonstrating the change.
Here I set the Button type to "Custom" to remove the border and background.
Here I set the Top and Left in the Edge set for "Title" (Title is an option in the drop down)
EDIT
Newest Xcode has moved the size settings to a new location
Just put the image in the background field instead. This way the text will appear in front of the image.
It sounds like you are setting the image for the button but not the background image so reverse that.
I noticed that if the UIButton colour is set to default, adding an image makes it white and thus invisible. Changing the colour manually makes it visible again.
I'm creating a popup panel whit same text, i would like to disable the background and make it grey. I read about setGlassEnabled but it doesn't work, can someone help? ps. the popup is correctly visualized.
PopupPanel popup = new PopupPanel(infoType);
popup.center();
popup.setGlassEnabled(true);
popup.show();
The glass panel has no default style, so it's transparent by default. If you want the background to be grayed out, you need to add some CSS styling to the glass panel.
Also, setGlassEnabled only enables the glass panel for the next time the popup is shown, and in your case, the popup is already showing when you call show (because of the previous call to center), so it's a no-op and the glass panel actually isn't used. Move your call to center to after the call to setGlassEnabled and/or call hide before setGlassEnabled.
Putting the following code at the top of your dialog constructor appears to fix the issue for me.
setGlassEnabled(true);
Style glassStyle = getGlassElement().getStyle();
glassStyle.setProperty("width", "100%");
glassStyle.setProperty("height", "100%");
glassStyle.setProperty("backgroundColor", "#000");
glassStyle.setProperty("opacity", "0.45");
glassStyle.setProperty("mozOpacity", "0.45");
glassStyle.setProperty("filter", " alpha(opacity=45)");
The javadoc for setGlassEnabled() is a bit misleading by saying that "the background will be blocked with a semi-transparent pane". In fact all it will do is apply a full-screen div with a default style name of 'gwt-PopupPanelGlass' (as of GWT 2.4, at least). If, say, your project <inherits> a theme such as com.google.gwt.user.theme.clean.Clean, then clean.css supplies the semi-transparent pane you were expecting:
.gwt-PopupPanelGlass {
background-color: #000;
opacity: 0.3;
filter: alpha(opacity=30);
}
Otherwise, as previously described, you'll have to roll your own.
I want to have a static footer image with 5 buttons for navigation in my mobile phone website. The image is here http://www.pintum.com.au/jm/footer3a.jpg. The blue icons should be the default, the yellow icon should only be visible for the hover or active state.
I want to know how can I make this image scale to the correct width on all mobile devices (landscape and portrait) and have links to other pages and make the current/active pages icon the yellow color?
What I have tried so far
I first tried to make a CSS Sprite but that go ugly (complex) quickly. Painful working with widths everywhere so the image scales correctly as I had no way of knowing the height in pixels since the width is dynamic. I could use JS to find the width and calculate height on the fly. But this sounds like overkill.
Next I tried to have a single image with a width of 100% then place div overlays on top of the image. But with this solution I could not figure out how to navigate pages using JavaScript click event, or figure out how I would be able to change the image icon on the selected page http://jsbin.com/uraya5/3/ . And detrmining the correct height for the div
Last I tried to make each button a seperate image. These seems like the easist soultion. But jQuery Mobile adds a bunch of extra styles to the button I do not know how to remove. See http://jsbin.com/uraya5/4
So whats the best/easiest way to do this?
How can I remove the style around
links?
Or can I use a single image CSS sliding door method? To reduce HTTP request.
Ok I figured it out
See soultion here http://jsbin.com/uraya5/10/
I had to:
Set width to 19% of each button for
some reason there is spacing between
each button so 20% does not work.
Set ui-bar-a background to black so
it hides the spaces between my
images
Use this JS code to navigate pages $.mobile.changePage($("#about"),
"flip", true, true);
I would still like to use a single image instead of having 5 different images to reduce http calls. So if anyone finds a eligant soultion for this please let me know.
