C++ (Cpp) findCursorPos Examples

Example #1

File: uitextedit.c Project: Fluray/OrzOs

static void textEditMiceEvent(struct OzUIWidget *widget, struct OzUIMiceEvent *miceEvent)
{
    struct OzUITextEdit *textEdit;
    struct Rect cursorRect;
    if (miceEvent->type == OZUI_MICE_EVENT_DOWN) {
        textEdit = (struct OzUITextEdit*)widget->d;
        getCursorRect(textEdit, &cursorRect);
        OzUITextEditSetCursorPos(textEdit, findCursorPos(textEdit, miceEvent->x, 
                    miceEvent->y + textEdit->layout->height));
    }
}

Example #2

File: Console.cpp Project: watertoeast/telnet

// Erases everything from the current cursor position to the end of the line
bool Console::eraseToEndOfLine(void)
{
	cout.flush();
	findCursorPos();

	for(int i = xPos; i < 80; i++)
		cout << " ";
	cout.flush();
	setCursorPos(xPos, yPos);
		
	return true;
}

Example #3

File: Console.cpp Project: watertoeast/telnet

// Erases everything from the cursor position to the end
bool Console::eraseFromCursorToEnd(void)
{
	cout.flush();
	findCursorPos();
	DWORD numCharactersWritten;
	COORD consoleCoords = {xPos, yPos};
	FillConsoleOutputCharacter(consoleHandle, ' ', (25 - yPos) * 80 + (80 - xPos), consoleCoords, &numCharactersWritten);
	FillConsoleOutputAttribute(consoleHandle, consoleInfo.wAttributes, (25 - yPos) * 80 + (80 - xPos), consoleCoords, &numCharactersWritten);
	setCursorPos(xPos, yPos);
	cout.flush();
	
	return true;
}

Example #4

File: Console.cpp Project: watertoeast/telnet

// Erases everything from (0,0) to the cursor position
bool Console::eraseFromStartToCursor(void)
{
	cout.flush();
	findCursorPos();
	DWORD numCharactersWritten;
	COORD consoleCoords = {0, 0};
	FillConsoleOutputCharacter(consoleHandle, ' ', 80 * yPos + xPos, consoleCoords, &numCharactersWritten);
	FillConsoleOutputAttribute(consoleHandle, consoleInfo.wAttributes, 80 * yPos + xPos, consoleCoords, &numCharactersWritten);

	setCursorPos(xPos, yPos);
	cout.flush();

	return true;
}

Example #5

File: Console.cpp Project: watertoeast/telnet

// Erases the entire line that the cursor is on
bool Console::eraseEntireLine(void)
{
	cout.flush();
	findCursorPos();
	unsigned char tempX = xPos;
	
	setCursorPos(0, yPos);

	for(int i = 0; i < 80; i++)
		cout << " ";

	cout.flush();
	setCursorPos(tempX, yPos);
	
	return true;
}

Example #6

File: Console.cpp Project: watertoeast/telnet

// Erases everything from the start of the current line to the cursor position
bool Console::eraseFromStartOfLineToCursor(void)
{
	cout.flush();
	findCursorPos();
		
	unsigned char tempX = xPos;
	
	setCursorPos(0, yPos);

	for(int i = 0; i < xPos; i++)
