List view with simple cursor adapter items checked are un-checked during scroll

由 给你一囗甜甜゛ 提交于 2020-01-21 21:21:45
问题 I have problem that I couldn't find answer on SO - all problems solved on SO where about too much different issue and didn't work. Problem is - 1. Clicked rows in ListView (after click they are marked with blue coolor background, and checked box) loose their marks of beeing clicked (checked checkbox and color) after scrolling. 2. Even more - other rows are marked during scroll even that are not clicked. ListView is bound to my Custom Simple Cursor Adapter which gets data from SQLite database.

Sending Programmatic Mouse Events to X

由 邮差的信 提交于 2020-01-21 13:58:24
问题 I am somewhat new to X development on Linux. I'm wondering what are best practices (or links to resources) for programmatically sending cursor events. Moving the cursor to a normalized (X,Y), creating right/left mouse clicks, etc. Ideally this would be something in C/C++ . I have played around with the Qt QCursor but I'd like to know the raw way to accomplish this. 回答1: I think you can use XSendEvent. There's some sample code here which uses XQueryPointer to populate most of the event fields.

Oracle - using bind variable in LIKE clause of dynamic cursor

由 老子叫甜甜 提交于 2020-01-21 04:57:05
问题 I am using dynamic cursor for fetching data. Query that is being executed looks similar to: query := 'SELECT column1, column2 FROM my_table WHERE column1 LIKE ''%:bv1%'''; And the cursor itself is executed like this: OPEN my_cursor FOR query USING my_var1; I also tried to check the query and print it: ... WHERE column1 LIKE '%:bv1%' ... so apostrophes are escaped, but the cursor fetches no data. Is it even possible to use bind variables in LIKE clause and if yes, what did I do wrong? 回答1:

问题 I have created three checkbox controls for three threads and each would start by checking a checkbox control.

How do i play a song from library when the preloader is a “x”% of total loaded?

问题 I am currently undertaking a final exam based on the presentation of an offline portfolio and I need to make a preloader, where when the process of loading is 25% of total bytes, to play a sound that is imported into the library. I've tried several ways and can’t do it. I'll leave you the code for my preloader. //(also this code is a mouse loader in text form) this.loaderInfo.addEventListener(ProgressEvent.PROGRESS,checkingProgress); function checkingProgress(event:ProgressEvent):void{ var
