Make WPF/SL grid ignore a child element when determining size

阅读更多关于 Make WPF/SL grid ignore a child element when determining size

问题 I have a Grid which has several children, one of which is a ScrollViewer. I want the Grid to size itself based on all of its children except the ScrollViewer, which I want to just take up the space that is created by sizing the Grid for the rest of its children. (For example, the Grid is 2x2 and the ScrollViewer is in Row 0, Column 0, and so the other three Grid entries are enough to determine the dimensions of the Grid.) Is there a nice way to do this? I've looked into creating a Custom

问题 It's my very first question here and i hope you can help me. I'm trying to set up a product-overview page with the bootstrap grid. I have got 4 products in a row for large screen sizes. For smaller screen sizes i'd like to have 2 products per row. The trick is, i want to have the product details in a collapsed container between the rows, that opens up, when i click on a product. It's working for the large screen sizes with 4 products. But how to achieve that the collapsed container is showing

Use ScrollViewer inside another Scrollviewer

阅读更多关于 Use ScrollViewer inside another Scrollviewer

问题 The structure of my wpf application is like: <Scrollviewer> <Grid> <Scrollviewer> <DataGrid> My Goal is, if the DataGrid exceeds the height of the screen to use it's own Scrollviewer. At the Moment only the outside ScrollViewer is used and so i have to scroll the whole Grid. Can someone please tell me how to do this? 回答1: You need to set a height on the inner ScrollViewer, otherwise it'll stretch as much as it needs based on it's content's size. <Window x:Name="RootWindow"> <ScrollViewer>

Swift: How to declare a 2d array (grid or matrix) in Swift to allow random insert

阅读更多关于 Swift: How to declare a 2d array (grid or matrix) in Swift to allow random insert

问题 I need to be able to store information about cells in a 2d matrix or grid. Data is not contiguous so I may need to store data at 5,5 when there is no data at lower rows and columns. My first thought was an array of arrays dynamically sized. But Swift arrays have bounds that do not grow automatically. If I attempt to place something at index 5 and thats beyond its current size it fails with out of bounds exception. Is there a collection class in Swift or Cocoa which supports random access to a

OpenGL - How to calculate normals in a terrain height grid?

阅读更多关于 OpenGL - How to calculate normals in a terrain height grid?

My approach is to calculate two tangent vectors parallel to axis X and Y respectively. Then calculate the cross product to find the normal vector. The tangent vector is given by the line that crosses the middle point on the two nearest segments as is shown in the following picture. I was wondering whether there is a more direct calculation, or less expensive in terms of CPU cycles. You can actually calculate it without a cross product, by using the "finite difference method" (or at least I think it is called in this way). Actually it is fast enough that I use it to calculate the normals on the

How to create a self resizing grid of buttons in tkinter?

阅读更多关于 How to create a self resizing grid of buttons in tkinter?

I am trying to create a grid of buttons(in order to achieve the clickable cell effect) with Tkinter. My main problem is that I cannot make the grid and the buttons autoresize and fit the parent window. For example, when I have a high number of buttons on the grid, instead of shrinking the buttons so that the grid fits inside the window, I get a stretched frame that goes off screen. The effect that I am looking for is the grid filling all available space, then resizing its cells to fit within that space. I have read at the documentation, but I still cannot figure out how to make it work. This

I am trying to plot counts in gridded plots, but I am not being able to figure out how I go about it. I want to: Have dotted grids at an interval of 5 Have major tick labels only every 20 I want the ticks to be outside the plot. Have "counts" inside those grids I have checked for potential duplicates such as here and here , but I have not been able to figure it out. This is my code. import matplotlib.pyplot as plt from matplotlib.ticker import MultipleLocator, FormatStrFormatter for key, value in sorted(data.items()): x = value[0][2] y = value[0][3] count = value[0][4] fig = plt.figure() ax =

Copy jTable row with its grid lines into excel/word documents

阅读更多关于 Copy jTable row with its grid lines into excel/word documents

Is it possible to copy jTable row and paste it into word document or in a new email with its formatted grid (colored horizontal and vertical grid lines).. If yes, how? When I copy a row from jTable and paste it into word document, Word recognizes it as a table row but I have to style it by adding grid lines and coloring them This is a VERY simply example of copying a row of data into a HTML based table. I was able to copy any row and paste into word as a HTML based table without (to many) issues import java.awt.EventQueue; import java.awt.Toolkit; import java.awt.datatransfer.Clipboard; import

When editing a grid, how do I disable specific fields by row?

阅读更多关于 When editing a grid, how do I disable specific fields by row?

问题 I have a kendo grid with data in it and multiple columns (say col 1, 2, and 3). Columns 1, 2, 3 need to be able to be edited (or preventing editing) based off the values of each other. This is row specific. For instance, if column 1 (date) is < column 2 (date) then column 3 is not allowed to be edited. I know it's simple enough to disable or enable an entire column but my requirements are row specific. So row 1 could have column 3 enabled and row 2 could have column 3 disabled. Any thoughts?
