When i do this:
void test(){|}
The caret is between {}, and then i press enter and this happen:
void test(){
|}
This is the problem, when i create a method, the caret is always before }, so i have to press enter again and again, just to put the caret in the right place.
What i want is exactly what happen with if():
if(){|}
And after press enter:
if(){
|
}
How can i make sure that the position of the caret, for any method, looks like the position of the caret in if() method?
I'm using codeblocks 16.01.
Thank you.

Hello guys i really need your help . I want to make some program in javafx so i need to add listener to random generated button on the keyboard. For example :
i don't want to add some action if user type enter but i want to add action to some random button and nobody would know which is that button . so the user need to click every single button on the keyboard to find out which is that button.How would he knows that this is the correct button ? - > well the program will be executed , when he click on the wrong button -> nothing will happen.
Try something like this:
private void handleKeyPress(KeyEvent ke) {
String text = ke.getText();
KeyCode code = ke.getCode();
if ( ke.isControlDown() || ke.isMetaDown() ) {
//DO something for example
}
}
I use a custom keyboard which contains a delete and a clear button.I can able to delete the letters using this code
let obj = UIInputViewController()
(obj.textDocumentProxy as UIKeyInput).deleteBackward()
Is it any keyword available to clear whole text in a textfield.
NB: I found this link but it is not apt for my requirement
There is no keyword available for deleting the whole text in the textfield through custom keyboard.
To clear all the text that the UITextDocumentProxy object can access in the textfield before the cursor position
if let word:String = self.textDocumentProxy.documentContextBeforeInput
{
for _: Int in 0 ..< word.characters.count {
self.textDocumentProxy.deleteBackward()
}
}
To delete the text after cursor position, you have to move the cursor forward to delete it.
Does anyone know if there's a way in Visual Studio 2010 with ReSharper 6.1 to comment out the selected lines of code with their closing brackets - or simply to comment out both the highlighted opening bracket and it's corresponding closing bracket? Here's an example of what I mean:
if(something) {
do(this);
}
I am looking for a hot-key so that when if(something) { is selected, it will comment out if(something) { and }, preferably fixing the tabs once commented like so:
// if(something) {
do(this);
//}
This isn't entirely what you're after, but it's pretty close:
Highlight the code inside the if statement by placing the cursor at one brace and hitting Ctrl + Shift + ].
Now hit Ctrl + Shift + Alt + Left Arrow. This will move the code 'left', i.e. outside of the if statement.
You don't need to comment the if statement out after this because it's empty.
Note that you can also move code 'right' to put it back in the if statement later.
I wish to capitalize the first letter of a sentence, on-the-fly, as the user types the text in a CKEditor content instance.
The strategy consists in catching each keystroke and try to replace it when necessary, that is for instance, when the inserted character follows a dot and a space. I'm fine with catching the event, but can't find a way to parse characters surrounding the caret position:
var instance = CKEDITOR.instances.htmlarea
instance.document.getBody().on('keyup', function(event) {
console.log(event);
// Would like to parse here from the event object...
event.data.preventDefault();
});
Any help would be much appreciated including a strategy alternative.
You should use keydown event (close to what you proposed):
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() === 65 /*a*/ && isFirstLetter()) {
// insert 'A' instead of 'a'
editor.insertText('A');
event.data.preventDefault();
}
});
Now - how should isFirstLetter() look like?
You have to start from editor.getSelection().getRanges() to get caret position.
You're interested only in the first range from the collection.
To extract text content from before the caret use small trick:
move start of the range to the beginning of document: range.setStartAt( editor.document.getBody(), CKEDITOR.POSITION_AFTER_START ),
use CKEDITOR.dom.walker to traverse through DOM tree in source order,
collect text nodes and find out what's before caret (is it /\. $/) - remember that you have to skip inline tags and stop on block tags - hint: return false from guard function to stop traversing.
Example of how you can use walker on range:
var range, walker, node;
range = editor.getSelection().getRanges()[0];
range.setStartAt(editor.document.getBody(), CKEDITOR.POSITION_AFTER_START);
walker = new CKEDITOR.dom.walker(range);
walker.guard = function(node) {
console.log(node);
};
while (node = walker.previous()) {}
And now few sad things.
We assumed that selection is empty when you type - that doesn't have to be true. When selection is not collapsed (empty) then you'll have to manually remove its content before calling insertText. You can use range#deleteContents to do this.
But this is not all - after deleting range's content you have to place caret in correct position - this isn't trivial. Basically you can use range#select (on the range after deleteContents), but in some cases it can place caret in incorrect place - like between paragraphs. Fixing this is... is not doable without deeeeeeeep knowledge about HTML+editables+insertions+other things :).
This solution is not complete - you have to handle paste event, deleting content (one can delete words from the start of sentence), etc, etc.
I guess there are couple of other problems I didn't even thought about :P.
So this approach isn't realistic. If you still want to implement this feature I think that you should set timer and by traversing DOM (you can use walker on range containing entire document, or recently typed text (hard to find out where it is)) find all sentences starting from lower letter and fix them.
This is what worked for me in Ckeditor 4.
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() >= 65 && event.data.getKeystroke()<=91 && encodeURI(this.getText())=="%0A" && this.getText().length==1 ) {
//uppercase the char
editor.insertText(String.fromCharCode(event.data.getKeystroke()));
event.data.preventDefault();
}
});
I am trying to get a script like this in AHK but I don't know how to write it in AHK:
string arrow
if (leftArrowKeyPressed) {
arrow = "left"
}
if (rightArrowKeyPressed) {
arrow = "right"
}
if (arrow = "left") {
for (int number = 1000; number < 10000; number++) {
simulateKeyPresses(number)
simulateKeyPresses(mousebutton0)
}
}
I did something similar to this. It uses the While command. Your code might look something like the following:
~left::
While GetKeyState("left", "P") {
Send {NUMBER}
Send {MOUSE_BUTTON}
}
Line 1: '~left::' tells the following lines of code to activate when the left button is pressed. The '~' tells the program to still allow the 'left' arrow key to work. If you wanted this code to run and simultaneously block the 'left' arrow from working, remove the '~'.
Line 2: 'While GetKeyState("left", "P")' is self-explanatory. It's a 'while' loop that runs as long as you are holding the 'left' arrow key.
Line 3 and line 4 are for your code to go. Note that 'NUMBER' can be replace by any number 0-9, and 'MOUSE_BUTTON' can be replaced by either the left mouse button (LButton) or the right mouse button (RButton).
I hoped this helped get you started. Also, as formentioned, the AHK Help manual is very informative. You can search 'AutoHotKey Help' on your computer for your off-line version, or visit this link for the online version. These manuals include documentation of just about anything you could ever hope for, as well as a useful example of code at the bottom of each page.
