Closed 6 years ago . How can I get the bottom left coordinate, i.e. the maximum y coordinate, of a view in obj-c and Swift? 回答1: Supposing that you're talking about UIView , you may want to look at the CGGeometry reference. Talking about 'left' and y coordinate doesn't make much sense, but for instance CGRectGetMaxY

Or you can try to execute this command through adb in your PC. 来源: https://stackoverflow.com/questions/29326532/how-to-click-on-a-special-coordinate-android-screen

问题 I'm studying iOS' UIView! And I found that I can't understand how bounds works. For example, Please run this code ... and see red box's moving. The red box goes up! and white root view is static! Why!? why red box goes up! ?? please let me know OTL! class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let childView : UIView = UIView(frame: CGRect(x: 50, y: 50, width: 200, height: 200) ) childView.backgroundColor = UIColor.red self.view.addSubview

Java MouseEvent position is inaccurate

耗尽温柔 提交于 2019-12-18 18:27:06
问题 I've got a problem in Java using a "canvas" class I created, which is an extended JPanel , to draw an animated ring chart. This chart is using a MouseListener to fetch click events. The problem is that the mouse position does not seem to be accurate, meaning it does not seem to be relative to the "canvas" but instead relative to the window (in the left, upper corner I got about 30px for y coord). This is my code: I created a class, that extends JPanel and does have a BufferedImage as member.

How to get 3D coordinate Axes of head pose estimation in Dlib C++

只谈情不闲聊 提交于 2019-12-17 15:52:18
问题 Dlib C++ can detect landmark and estimate face pose very well. However, how can I get 3D coordinate Axes direction (x,y,z) of head pose? 回答1: I was also facing the same issue, a while back ago, searched and found 1-2 useful blog posts, this link would get you an overview of the techniques involved, If you only need to calculate the 3D pose in decimal places then you may skip the OpenGL rendering part, However if you want to visually get the Feedback then you may try with OpenGL as well, But I

How to create adjacency matrix from grid coordinates in R?

会有一股神秘感。 提交于 2019-12-12 13:01:54
问题 I'm new to this site. I was wondering if anyone had experience with turning a list of grid coordinates (shown in example code below as df). I've written a function that can handle the job for very small data sets but the run time increases exponentially as the size of the data set increases (I think 800 pixels would take about 25 hours). It's because of the nested for loops but I don't know how to get around it. ## Dummy Data x <- c(1,1,2,2,2,3,3) y <- c(3,4,2,3,4,1,2) df <- as.data.frame

Get UITextField Y coordinate on UIView level?

烈酒焚心 提交于 2019-12-12 10:54:59
问题 Currently I have a UITextField in a custom cell and I want to get the Y coordinate of that UITextField on the level of the View Controller's view (UIView). Currently I am trying to do something like this: if (thetextField.superview.superview.superview.frame.origin.y >= keyboardY) { } But it seems that the Y coordinate is always 0 when it is in fact not. Is there any way to achieve this? I am doing this because I want to detect whether the UIKeyboard is blocking the UITextField on the UIView

Why can't this code produce a points layer in GeoTools

问题 I am testing adding a collection of points to a map utilizing the Geotools API. I've been following this example as best I could Problem creating a point and adding it to FeatureCollection, as the example code is old, and things like FeatureCollections is deprecated. I tried using DefaultFeatureCollection instance instead, and I am not sure if I am using it correctly, and that is why the points do not appear on the map. What am I doing wrong? Here is some of my code: private void plotMarkers(
