The height of your scrollbar didn’t match the buttons frame height because you did’t tell it to stick North and South .grid(…, sticky=’ns’) Then, the scrolling behavior you want to achieve is described here: Adding a Scrollbar to a group of widgets See also @martineau‘s answer for a more general object-oriented solution with 2D scrolling … Read more
This is due to varying column height. You need a “clearfix” reset every 3 columns to force even wrapping. One way is to use the approach recommended by Bootstrap, or in this specific case you can use a simple CSS clearfix like this.. @media (min-width:992px) { .auto-clear .col-md-4:nth-child(3n+1){clear:left;} } Demo: http://codeply.com/go/mONLiFj30T For other “clearfix” scenarios … Read more
There’s a method on the DataGridView called “Sort”: this.dataGridView1.Sort(this.dataGridView1.Columns[“Name”], ListSortDirection.Ascending); This will programmatically sort your datagridview.
Matplotlib has the imshow method for plotting arrays: import matplotlib as mpl from matplotlib import pyplot import numpy as np # make values from -5 to 5, for this example zvals = np.random.rand(100,100)*10-5 # make a color map of fixed colors cmap = mpl.colors.ListedColormap([‘blue’,’black’,’red’]) bounds=[-6,-2,2,6] norm = mpl.colors.BoundaryNorm(bounds, cmap.N) # tell imshow about color map … Read more
Firstly, an apology. In my answer to your last question, CreateCellControl should have called inherited to create the cell. I’ve amended my answer. As for this question, I’ve uploaded my blog posting on FireMonkey Cells – http://monkeystyler.com/blog/entry/firemonkey-grid-basics-custom-cells-and-columns – it covers the stuff from the previous answer, and also covers creating custom cell controls. You’ll need … Read more
Don’t use paint, use paintComponent and don’t forget to call super.paintComponent JComponent may not be the best choice, JPanel is probably a better choice What’s wrong with Graphics#fillRect(int, int, int, int)? You might to take a look at Performing Custom Painting and 2D Graphics for more details. I’d advice against trying to have a second … Read more
For the fun of it, I wrote an ImageGrid component for you. It has only a vertical scroll bar; resizing the width of the control adjusts the column count and row count. The images are cached as resized bitmaps in an internal list, along with their file names. Because loading and resampling these images may … Read more
Call the width and height of the input array W and H respectively. Run this clever O(WH) algorithm for determining the largest rectangle, but instead of tracking just the single largest rectangle, for each (x, y) location record in a W*H matrix the width and height of (one or all of) the largest rectangles whose … Read more
Your best bet in my opinion would be to use the gridView that way it supports scrolling and spacing and you can be very dynamic in what each items layout and events are. Another option is to just create a lay out the images with a combination of Relative/Linear Layouts. GridView layout: <GridView xmlns:android=”http://schemas.android.com/apk/res/android” android:id=”@+id/myGrid” … Read more
GridLayout has indeed been backported to be compatible with API level 7 and up. It’s (sort of) part of the support library. After you’ve downloaded the support library, you’ll find an Android library project in your local sdk folder located at: <sdk_folder>\extras\android\compatibility\v7\gridlayout Set it up as dependency of the project you’re working on. After that, … Read more
