cursor

问题 I have a paint application program I have programmed from scratch in processing.js and incorporated it into my markdown code on my GitHub page. This means I would prefer to not use CSS (I would have to link to a JavaScript program that creates a link element to the CSS file and appends it to the head). In the paint program, there is an eraser that just paints the background, but I want it to look more like they are using an eraser by changing the cursor to the eraser when they have the eraser

问题 I would like to move my cursor to the start of the text in my ComboBox . This is what it looks like at the moment: I did try the following on the Closed Event : cboSomeCombo.Select(cboSomeCombo.Text.Length, 0); The cursor still stays all the way to the right. 回答1: This seems to be related: How to set the selected text of combobox align left 来源： https://stackoverflow.com/questions/5456976/how-to-move-my-cursor-to-the-left-in-in-my-combobox

问题 I am looking for a way to do 2 very basic things. I just want to retrieve the position of the caret in the text. Then I want to position the caret in a specific position in the text. The purpose is to be able to programmatically modify the text. I have found many people who were trying to do various similar things but not quite what I wanted. In fact, most solutions are looking into the HTML, finding ranges and DOM elements. Maybe that is the way to go but I haven't found a working solution.

问题 Is there any possibility to change marker form and size for data cursor in Matlab? I mean it is black and square by default. I would like to change it to blue and circle, for example. I've found only how to customize text of data tips. Thank you. 回答1: Yes - marker options are included in the properties of the undocumented graphics.datatip object class. These objects are accessible as hidden properties of the graphics.datacursormanager objects accessible through the documented datacursormode

问题 I'm implementing panning of a large image in a PictureBox control, and I have no problem setting the appropriate directional pan cursors. However, I can't seem to find the image used for the origin of the pan (a circle with arrows inside of it). Where can I find it? 回答1: I think the image that you are looking is not included in the framework. Every app uses their own cursor for that (AFAIK). The closest you can get is using Cursors.SizeAll as Hans Passant already told you: this.Cursor =

问题 I am writing a stored procedure which opens a cursor to a table and then iterate through all records. In the iterating process I create a dynamic query based on the results of first cursor. I need to open the cursor on dynamic sql, but MySQL is not allowing to do me so, as accoriding to the official doc of mysql "Cursors must be declared before declaring handlers.

I want use .ani file but it's only work in IE. cursor: url(../img/mcursor.cur),auto; 回答1: IE supports .ani and .cur using Windows APIs. Webkit/Blink and Firefox have their own parsers for .cur (see ICOImageDecoder and nsICODecoder), but they do not have parsers for the ani format (as evidenced by no results from a code search for [ANIHEADER] etc.) See Animated cursor support in web applications? for

问题 I need to hide the cross-shaped cursor that OpenCV shows when moving the mouse over an image window. Does anybody know if it is possible? I wanted to add a screenshot, but unfortunately the mouse cursor is not shown in screenshots. Thanks! 回答1: I don't think it's possible with only OpenCV, you have to use OS API or eventually you may use QT(http://www.codeprogress.com/cpp/libraries/qt/QtHideMouseCursor.php#.UjGpZD-rGoE) - it's quite easy to use it with OpenCV. 来源： https://stackoverflow.com

问题 I want to fill a list with data from a cursor this way: myCursor = myDBA.getAllCompanies(); startManagingCursor(myCursor); myListAdapter = new SimpleCursorAdapter(this, R.layout.company_row, myCursor, FROM, TO); myListAdapter.setViewBinder(VIEW_BINDER); companiesListView.setAdapter(myListAdapter); I use a custom ViewBinder to fill two TextViews and one ImageView in each row: private final ViewBinder VIEW_BINDER = new ViewBinder() { /** * Binds the Cursor column defined by the specified index
