Putting objects onto Frames

倾然丶 夕夏残阳落幕 提交于 2020-06-28 05:47:05
问题 I am creating a simple die rolling simulation that rolls dice when a button is pressed. I didn't add the action listener yet because I have a problem with showing up an object onto my frame. I created a class that generates a dice and gets an image of the dice with the number rolled but I can't seem to add the object onto my frame. public class DieFrame extends JComponent { private static final int FRAME_WIDTH = 500; private static final int FRAME_HEIGHT = 240; private JButton rollButton;

Why doesn't a local name with a PhotoImage object work, for a tkinter label image?

问题 I have created a python class which inherits Tk from tkinter library. I want to add a label with an image to it but it only works when I create a Photoimage as variable to 'self'. This code works: class HMIDrawer(Tk): def __init__(self): super().__init__() self.frame = Frame(self) self.img = PhotoImage(file='resources/platoontomtom_empty.png') self.label = Label(self.frame, image=self.img, bg='white') self.label.pack() self.frame.pack() self.mainloop() And this code doesn't work: class

show a page inside a window in XAML

*爱你&永不变心* 提交于 2020-03-18 05:07:47
问题 I have a tabcontrol in my window, inside each tabitem I want to have a different page. I can achieve this by making a Frame inside the TabItem and in the behind code use for example: frame1.Content = new Pages.MyPage() How can I do the same thing in XAML? 回答1: <TabItem> <Frame Source="MyPage.xaml" /> </TabItem> 回答2: you probably don't need the frame. Something like this should work. <TabControl> <TabItem> <MyPage Name=frame1 /> </TabItem> <TabItem> <MyPage Name=frame2 /> </TabItem> <

move up a frame, debug R environment

无人久伴 提交于 2020-01-30 16:03:11
问题 When debugging a function, I would like to move up to the parent frame and look at some variables there. How do I do this? Here is a sample: f <- function() { x <-1 g(x+1) } g <- function(z) { y = z+2 return(y) } I then debug both functions using debug("g") and debug("f") . When I end up in g at the Browser> , I would like to move back up to f to examine x. Thanks 回答1: In R terminology, you are wanting to investigate the parent frame of g() 's evaluation environment (i.e. the environment in

Change frame and label colors on an item selected - syncfusion listview xamarin forms

问题 I have been trying to change the color of the first item of my list[0] and also when I tapped on an Item - the color I need to change is the frame and the labels inside it. I tried the following: BackgroundColor="{Binding IsActive, Converter={StaticResource colorConverter}}" This works at the list level only, but nothing inside the data template. What else could I do? <sync:SfListView x:Name="list" SelectionMode="Single" SelectionGesture="Tap" ItemTapped="Day_ItemTapped"> <sync:SfListView
