问题 I am trying to learn how to use the HTML canvas element, and naturally, I am making a drawing application. So, I have the code set up for the actual drawing and animating part of the app, but I am not sure how to approach getting the position of the mouse cursor. I really would prefer not to use jQuery, for I would rather not want to learn all of what it does and have to go through the process of getting it set up. Thanks for any help! 回答1: function getMousePos(canvas, evt) { var rect =

There is a JTable in my application with resizable header columns. Normally when I move the cursor over table header for resizing, the cursor icon changes to resize arrow, like <-->. But things are different in the following scenario. There is a button action in the same Frame , and during action performed, I am setting the cursor to busy icon and change it back to default cursor once the action is completed, using Container.setCurosr(Cursor cursor) method. Sometimes if I move the cursor over table header of resizing, after a button action, the cursor icon does not change to resize arrow,

iOS: Programmatically move cursor up, down, left and right in UITextView

由 落花浮王杯 提交于 2019-12-01 05:38:47
问题 I use the following code to move the cursor position to 5 characters from the beginning of a UITextField : txtView.selectedRange = NSMakeRange(5, 0); Now, if I have a cursor at an arbitrary position as shown in the image below, how can I move the cursor up, down, left and right? 回答1: Left and right should be more or less easy. I guess the tricky part is top and bottom. I would try the following. You can use caretRect method to find the current "frame" of the cursor: if let cursorPosition =

问题 I am working on a function that will take a low number and a high number as paramaters and returns a table containing everything between (and including). I know I could use a cursor and increment a variable adding it to a scope based table every iteration, but I would prefer to avoid a cursor if possible. Does anyone else have a suggestion for a way to do this? (As i'm typing this im thinking possibly a CTE, which I will go investigate). 回答1: Just create an indexed permanent auxiliary numbers

Listen to any changes in a cursor in android

I would like to listen to any changes in a cursor.Is it possible to acheive this without using a contentprovider in android? Note:(I am not using any data adapter) Thanks I found that You don't need to use content Provider.When ever the data changes(like during insertions,deletions etc..) you can just call getContentResolver().notifyChange(Uri uri, ContentObserver observer) and set a contentObserver in your activity to listen for the change. As far as I know, if your changes in the cursor are due to requery() or some other method on the cursor like close(), then you can use a dataset observer

由 て烟熏妆下的殇ゞ 提交于 2019-12-01 05:22:11
I am using a while loop to iterate through a cursor and then outputing the longitude and latitude values of every point within the database.
