java - How to select all text in a JFormattedTextField when it gets focus? -

-

I have a small Java desktop app that uses swing to create a data entry dialog with some different input fields (Jetextfield, Jessimbox, JSPinner, JFormattextfield). When I activate JFormattedTextFields by tapping through the form or clicking with the mouse, I would like to select all the text that I want. In this way, users can simply start typing and overwrite the default values.

How can I do this? I have used a focus listener / focus adapter which selects all () calls on JFormattedTextField, but it does not select anything, although the Focus adapter's focus is called the grain () method (see code sample below) . 

  Private javax.swing.JFormattedTextField pricePerLiter; // {...} "" "" "" "" "" "" "" "" "" "" "" ... "0.000")); Formatter.setValueClass (double class);} return formater;}}); // ... PricePerLiter.addFocusListener (new java.awt.event.FocusAdapter () {Public Zero was focused (java.awt.event.FocusEvent evt) {pricePerLiter.selectAll ();}});

Any ideas? The interesting thing is that by choosing all your text, apparently the default behavior for both is JTextField and JSpinner, at least when tabbing through the form.

Wrap your call with SwingUtilities.invokeLater, after processing all pending att event This will be: 

  pricePerLiter.addFocusListener (new java.awt.event.FocusAdapter () {Public Zero Focused (Java.avt.evolution.focus event evt) {SwingUtilities.invokeLater (New Runnabal) {@Override Public run zero () {pricePerLiter.selectAll ();}}}}}});

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
