cursor

问题 I have a simple application that runs a process that can last for several minutes before completing. I am trying to provide an indication to the user that it is processing the request - such as changing the cursor to an hourglass. But I cannot quite get it to work right. All of my attempts have resulted in either an error or had no effect. And I seem to be calling the cursor shapes incorrectly, since PyQt4.Qt.WaitCursor returns an error that the module does not contain it. What is the correct

问题 I would like to change the cursor icon to my customized 32x32 image when a Java application is executing. I looked and searched, those I found are just setting cursor on a JComponent. But I want the cursor changed to my specified icon wherever it goes moving, browsing, and click, as long as the Java application is still running, or you can say program runtime. Thanks alot. 回答1: Standard cursor image: setCursor(Cursor.getDefaultCursor()); User defined Image: Toolkit toolkit = Toolkit

问题 Okay, so you know how in Windows Vista and Windows 7 MS changed the Hand Cursor (the one that shows up when you hover over a hyperlink), and added more detail to it so it's antialiased and nice and smooth around the edges? Well, why isn't it like that in Windows Forms apps? I'm sick off looking at a crappy hand cursor that looks like it was drawn by a caveman, is there a way to programmatically tell it to display the one that's actually installed in the system? I looked in the Cursors folder

问题 I'm trying to use cursors for a query that joins multiple tables. I've seen that for oracle there is a cursor based record. When I try the same for Postgres, it throws some error. How can I do the same in Postgres? CREATE OR REPLACE FUNCTION avoidable_states() RETURNS SETOF varchar AS $BODY$ DECLARE xyz CURSOR FOR select * from address ad join city ct on ad.city_id = ct.city_id; xyz_row RECORD; BEGIN open xyz; LOOP fetch xyz into xyz_row; exit when xyz_row = null; if xyz_row.city like '%hi%'

问题 I have a cursor containing several columns from the row it brings back that I would like to process at once. I notice most of the examples I've seeing on how to use cursors show them assigning a particular column from the cursor to a scalar value one at a time, then moving to the next row, e.g. OPEN db_cursor FETCH NEXT FROM db_cursor INTO @name WHILE @@FETCH_STATUS = 0 BEGIN --Do Stuff with @name scalar value, then get next row from cursor FETCH NEXT FROM db_cursor INTO @name END What I want

问题 This question already has answers here : How do I get the (x, y) pixel coordinates of the caret in text boxes? (3 answers) Closed 5 years ago . I was wondering if it is possible to find the exact location of the carret inside a textarea in pixels in relation to the entire page. For instance, if I have typed This is text into my text box, I would like to know the pixes from the top left of the screen to the carot. It would be in the form X: 200 Y: 100. This is so I can position a floating div.

问题 How can I assign color to the mouse cursor in a web-page? Can anyone suggest me a way to do it using any of the technologies e.g. HTML, CSS, JavaScript? 回答1: Use an image along with CSS cursor property, I don't see any need of JavaScript heere... Demo div { cursor: url(YOUR_IMAGE_URL), auto; } As commented, I've used auto which is nothing but default cursor just incase your image fails to load, exactly like we declare multiple font families. 回答2: Just to add the possibility to dynamically

问题 How can I fetch from a ref cursor that is returned from a stored procedure (OUT variable) and print the resulting rows to STDOUT in SQL*PLUS?
