grid

问题 I made this program where I am putting labels on a grid without saving them in a variable. I do this because then I can for loop through a list of classes and get the data from each class in and add them to a row. This is a small piece of it: self.collum = 0 for i in self.gui_resource_list: Label(text=i.get_name(), relief="groove", width=15).grid(column=self.column, row=0) Label(text=i.get_buyPrice(), relief="groove", width=15).grid(column=self.column, row=1) Label(text=i.get_salePrice(),

问题 What I have implemented till now in java is ask the user to upload an image from the directory. My next step is that when the image is loaded a grid is placed above that image just for visual purpose so that the image gets divided in a, say 10 x 10 grids. How do I implement this stuff? Here's what I have implemented till now. JFileChooser choose=new JFileChooser(); choose.showOpenDialog(null); File f=choose.getSelectedFile(); String filename=f.getAbsolutePath(); path.setText(filename);

问题 Following from this question, I have another query that I need to subtract a value of 10 from for all negative numbers in the data. Sadly, I'm just not sure how to implement the same subquery as is given in the previous question. The query in question is SELECT 10 * (c.customer_x / 10), 10 * (c.customer_y / 10), COUNT(*) as num_orders, SUM(o.order_total) FROM t_customer c JOIN t_order o ON c.customer_id = o.customer_id GROUP BY c.customer_x / 10, c.customer_y / 10 ORDER BY SUM(o.order_total)

问题 I'm basically having the same problem as this guy. The thing is, I want there to be a certain number of rectangles on the screen, depending on the screen size/resolution. Now the first comment on that question says "creating UI elements in procedural code in XAML-based technologies is discouraged, cumbersome, probably a bad idea, and just plain wrong". So is there another way in which I can achieve my goal? One way I can think of would be to have a minimum of 3x3 rectangles, but add UI code

问题 I have a check box model grid which is loaded from JsonStore. var drop_pick_grid = new Ext.grid.GridPanel({ store : dropPickGridStore, cm : new Ext.grid.ColumnModel([ selectModel, { sortable : true, header : "Drop/Pick Loc", dataIndex : 'locationName', width : 170, renderer : function(value, metaData, record, rowIndex, colIndex, store) { var refColor = record.data.tourTypeColor; //console.log(record); metaData.attr = 'style="background-color:' + refColor + ';"'; return record.get(

问题 I have a mesh of cells in memory. I know the width and height of the cells, X0,Y0, X1,Y1, X2,Y2. Given a line connecting (X1,Y1) to (X2,Y2) I would like a way to determine the cells crossed by this line. I have hashed the cells that should get sellected in my drawing. I would like an idea on how to solve this and i will build the implementation in PHP. 来源： https://stackoverflow.com/questions/30707433/cells-in-grid-crossed-by-a-line-php

问题 Basically, I want to make a grid with school subjects and all the test results I got from it, and I want to display about 10 results for every subject. Like this: ... -------------------------------------------------------------------- English| 7.4 | 6.4 | 9.5 | 4.5 | 8.9 | 3.9 | 8.0 | 6.5 | 9.9 | 4.9 | -------------------------------------------------------------------- Dutch | Results ... And I made basically two FOR loops, one reading every school subject out of a list and one that reads

问题 A client asked me to fix their image grid CSS. While I thought they just screwed around to much with the HTML for it to function properly it seems the problem is a bit more technical then I initially thought. Because I cannot think of the right keywords google isn't much help either. My problem is this: the banners are png's. And as you might figure, the bottom 3x1 banner should align to the bottom of the other 3x1 banner. This isn't really a problem if I'm working with columns (in this case

问题 I wonder if there is a proper approach to solve this situation. Imagine you are getting dynamic data into something like this: <ListView HasUnevenRows="True" ItemsSource="{Binding RecentSurveysList} " SelectedItem="{Binding Selected, Mode=TwoWay}" ItemSelected="ListView_OnItemSelected"> <ListView.ItemTemplate> <DataTemplate> <ViewCell> <StackLayout Orientation="Horizontal" Padding="20"> <Label Text="{Binding Id}" VerticalOptions="Start" Margin="0, 0 ,60 ,0"></Label> <Label Text="{Binding Date

问题 How can I get the absolute Row Height of the Grid object? If the return value in the Stars? GridLength l=grid.RowDefinitions[0].Height; if (l.IsStar==true) { //i need to convert from stars to absolute units <---- ? } 回答1: This will give you the ActualHeight of RowDefinition : grid.RowDefinitions[0].ActualHeight 来源： https://stackoverflow.com/questions/19546912/how-can-i-get-the-absolute-row-height-of-the-grid-object
