cursor-position

问题 This question already has answers here : Getting mouse position in c# (10 answers) Closed 6 years ago . help me please! :) My program should get cursor position (all screen) every ~50 ms and them write in text Box . How it make? Example: private void Form1_MouseMove(object sender, MouseEventArgs e) { textBox1.Text = e.X.ToString(); textBox2.Text = e.Y.ToString(); } but we get position only in window it's really do? 回答1: you can use Cursor.Position : textBox1.Text = Cursor.Position.X.ToString(

问题 I'm new in programming and currently learning about arrays in C. I'm making a puzzle that contains 15 numbered square pieces mounted on a frame and one piece is empty.It allow the user to hit any of the arrow keys(up,down,left,right).The user will continue hitting the arrow keys till the numbers aren't arranged in ascending order.These pieces can be move horizontally and vertically. My problem is that i don't know how to position the cursor.I know a library function gotoxy() but i think it

问题 I'm using Codeblocks to coding my things using C++. I remember that in C i can use gotoxy() features and textcolor(), but in C++ that library doesn't work. Any idea?... How can i use those functions in C++?. 回答1: gotoxy() and textcolor() are system dependent functions. They are not part of the standard and not portable. Two possibilities: with the same development environment you can get them to work in C and not in C++. In this case, its certainly conio2.h which doesn't provide for extern "C

问题 I have implemented an EditText where I wanted text to start from it's right, and I achieved by set gravity = right But the default cursor still shows up at the left of my text. This is what I have tried so far : and style sheet code for EditText Field. <style name="_style_user_profile_editText" parent="@android:style/Widget.EditText"> <item name="android:layout_width">match_parent</item> <item name="android:layout_height">wrap_content</item> <item name="android:layout_weight">1</item> <item

问题 I am wondering how you can change the cursor position in draft.js after having done an text insertion on key command. Therefore I am currently using _handleKeyCommand(cmd) to insert a custom text block whenever the user presses a specific button. Next I tried the following: currentState = this.state.editorState; var selectionState = this.state.editorState.getSelection().getStartKey(); this.setState({editorState: EditorState.forceSelection(currentState, selectionState)}); But this keeps

问题 Visual Studio tracks cursor positions and lets you move forward and backward through these positions. For example, you can type Ctrl+- to navigate backwards and Ctrl+Shift- to navigate forwards. I see that XCode tracks the history of which files you've visited, but does it also allow me to go forward and backward through the cursor locations? The reason I ask is because I find that by using Command-Double left click, I visit function definitions (often in the same file), and then I want to

问题 i want to get a cursor position from UITextview, i have implement the code in How to find a pixel-positon of a cursor in UITextView? post, the algorithm is based on algorithm in Pixel-Position of Cursor in UITextView. my problem is, i can't get the selectedRange.location value after keyboard appear in the 2nd time, cause it always tell that the value of location is 2147483647, which means not found. This is my implementation : -(void)getCursorPosition{ NSRange originalPosition = self
