edit-in-place

I have a ListView with 3 columns and would like to edit the third column, aka Subitem[1]. If I set ListView.ReadOnly to True, it allows me to edit the caption of the selected item. Is there an easy way to do the same thing for the subitem? I would like to stay away from adding a borderless control on top that does the editing. You can Edit a subitem of the listview (in report mode) using a TEdit, a custom message and handling the OnClick event of the ListView. Try this sample Const USER_EDITLISTVIEW = WM_USER + 666; type TForm1 = class(TForm) ListView1: TListView; procedure FormCreate(Sender:

Developing an extension for Mozilla Firefox I wonder if there is an "easier way" to what I do right now. Currently I do: Create a folder - in which to develop - for example myextension Inside this folder: Create and Edit the Files (like install.rdf, chrome.manifest, xul files. Basically all the other structure of a Firefox extension ( no problem here )) Zip-compress the content of the myextension to a ZIP-file (i.e. named myextension.zip) Rename myextension.zip to myextension.xpi Install the xpi-file-firefox-extension then in firefox Restart Firefox Test the extention After each edit to the

I have this system where I use ActiveAdmin to automate the backend and I was wondering if anyone tried to use in-place editing with tables for ActiveAdmin. I see some scenarios where that would be useful: key-value tables (like State, Category, etc.) and in master-detail views (Order and OrderItems)... Have anyone attempted to implement it? Any good pointers?

Is there a standard way to set up a table to allow editing-in-place, kind of like this: I only need editable text at the moment, but I might need UISwitches or UISliders in the future. Yep. Just add a UITextField , with its font and textColor set to appropriate values, as subviews of the table cell's contentView . You probably want to give the field a tag as well, so that you can easily grab a reference to it using the contentView 's -viewWithTag: method. With short forms you can get away with keeping an array of cells, one for each field, and handing them off to the table view without going

Is there a way to change the order of the columns in a numpy 2D array to a new and arbitrary order? For example, I have an array array([[10, 20, 30, 40, 50], [ 6, 7, 8, 9, 10]]) and I want to change it into, say array([[10, 30, 50, 40, 20], [ 6, 8, 10, 9, 7]]) by applying the permutation 0 -> 0 1 -> 4 2 -> 1 3 -> 3 4 -> 2 on the columns. In the new matrix, I therefore want the first column of the original to stay in place, the second to move to the last column and so on. Is there a numpy function to do it? I have a fairly large matrix and expect to get even larger ones, so I need a solution
