Now I want to add a UIView or UIButton over the map, like myLocation button style. There is any solution to add it and use it via storyboard?

问题 Can anyone tell me how to hook/overlay a DirectX game in C#? I've tried getting a fullscreen C# window to overlap a game, however it wont. After researching a little, I found out that I need to hook the game and then display the C# window. Can anyone explain how I would do this? Would I be able to display a C# form over a DirectX game? 回答1: (disclosure: I work for this company) You can try our Deviare API, it has functionality to hook COM objects from C#. It's a set of COM objects that can be

问题 I'd like to use a ScrollPane to display an image in its Viewport, and also have a grid (or box, or any other type of registration/location marker) overlay on the image. I need the overlay to remain fixed when scrolling (meaning the image seems to move "under" the overlay). I will be scrolling the View in the Viewport at a fixed rate to provide a smooth motion, and the overlay is to provide a reference to a certain location within the Viewport.

问题 I'm trying to draw some circle overlays containing text on MKMapView. I have subclassed the MKCircleView, in which I put the following (based on this), but the text does not appear.

问题 I have three questions actually: Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise, which one is better?

Sorry for the long list, but in the interest of learning, I would like to explore both the approaches. 回答1: I can't believe no one has answered this yet! A

问题 I'm attempting to overlap JPanel instances. Put a panel directly on another, in the exact same position and exact size. Every time I do this it moves the other panel to the other side or underneath, the previous panel is inside another much larger one and has buttons in it. How would I do this? Keep in mind it's using the Window Builder tool. 回答1: You might also want to look at OverlayLayout, seen here. It's not included in the conventional gallery, but it may be of interest. import java.awt

问题 I use PDFBox 1.8.8 and try to overlay a PDDocument with an other document by using the following scala method def mergeTest() = { val home = System.getProperty("user.home") val doc = PDDocument.load(home + "/tmp/document.pdf") val ovl = PDDocument.load(home + "/tmp/overlay.pdf") val ov = new Overlay() val mergeDoc = ov.overlay(ovl, doc) mergeDoc.save(home + "/tmp/result.pdf") doc.close() ovl.close() mergeDoc.close() } I have expected to get every page of "document.pdf" (N pages) overlayed
