问题 At design time in my UWP app, I've left enough room for everything I want (six buttons across the top and a TextBlock which will ultimately contain more text): Note too, the textBlocks at the bottom of the page. At runtime, the top TextBlock is terribly truncated, and all of the TextBlocks at the bottom of the form/page don't display at all, presumably for the same reason: If this is working as designed (by Microsoft, that is, not by me), what do I need to do to fall in line with the accepted

问题 When i'm setting the canvas width and height with css, the pen is beeing shifted. After zooming in/out in the browser (chromium), the pen isn't shifted anymore. I'm using the literally canvas widget and want to fit the canvas to its parent div. After initializing the canvas, i'm setting the width/height of the canvas with the jquery css function. But my pen isn't at the same coordinates. After scrolling in or out in my current browser, the pen is at the coordinates where my mouse pointer is.

问题 I am building a database and came across an issue that I need help in resolving. This database the customer wants to be able to link pictures to specific records. I have it so the pics are not OLE objects but links to a picture folder that will be on their network drive...So essentially the picture will be a hyperlink to the file path.... My question is does anyone know I way I can have the database reformat the picture automatically to 600 x 800 size, to help save space? We all know if I don

问题 I am trying to put the frames of a video in a deque. This code does not work. Because the back and front of the queue are both the same as the current frame. deque<Mat> frameSeq; int main() { Mat frame; VideoCapture video("path to video"); int key = 0; while (key != 'q') { video >> frame; frameSeq.push_back(frame); imshow("front", frameSeq.front()); imshow("back", frameSeq.back()); key = cvWaitKey(1); } return 0; } But when I resize the frame: deque<Mat> frameSeq; int main() { Mat frame;

问题 I want to know how to let a user resize a textbox themselves at runtime. Preferably the little tabs on the borders of the textbox would popup and they can drag to resize as per most apps. Is it possible to do this natively using winforms? if not is there a library to help do it? I would rather use native components if possible. All my google searches turn up false positives. 回答1: The simpliest solution by using the native components would be implementing you own custom-control using the

问题 I am receiving a warning in Qt about setting geometry every time I try to open a new window or Dialog. It even happens with QDialogInput . And I'm not trying to set the geometry, just calling the window already gives me a warning. Here's an example: main.cpp QLineSeries *series = new QLineSeries(); for(int i=0;i<graphPoints;i++) series->append(i,(qrand()%5)+20); QChart *chart = new QChart(); chart->legend()->hide(); chart->addSeries(series); chart->createDefaultAxes(); chart->setTitle("X vs Y

问题 How do I dynamically resize the a label or button, in particular, the text_size and height, depending on the amount of text, at run-time? I am aware that this question has already been answered in one way with this question: Dynamically resizing a Label within a Scrollview? And I reflect that example in part of my code. The problem is dynamically resizing the labels and buttons at run-time. Using, for example: btn = Button(text_size=(self.width, self.height), text='blah blah') ...and so on,

问题 Please refer to the code and comments below: vector<int> v1(10); cin>>v1[0]; // allowed cin>>v1[1]; // allowed // now I want v1 to hold 20 elements so the following is possible: cin>>v1[15]>>v[19]; // how to resize the v1 so index 10 to 19 is available. 回答1: You simply need to resize the vector before adding the new values: v1.resize(20); 回答2: You could use resize like this: v1.resize(20); 回答3: If you want to read as many values from cin as are available, you can use an istream_iterator

问题 I'm developing a grid based game in pygame, and want the window to be resizable. I accomplish this with the following init code: pygame.display.set_mode((740, 440), pygame.RESIZABLE) As well as the following in my event handler: elif event.type == pygame.VIDEORESIZE: game.screen = pygame.display.set_mode((event.w, event.h), pygame.RESIZABLE) # Code to re-size other important surfaces The problem I'm having is that it seems a pygame.VIDEORESIZE event is only pushed once the user is done

问题 The text image is very tiny, 17px x 10px in size It can be enlarge perfectly in MacOS let width = scale * image.size.width * kScale let height = scale * image.size.height * kScale super.init(frame: NSRect(x: 0, y: 0, width: width, height: height)) self.makeConstraints(width: width, height: height) self.drawBlock = { (context, bounds) in image.draw(in: bounds) } and redraw it: override func draw(_ dirtyRect: NSRect) { // Fill with optional background color. if let color = bgColor { color.set()
