QML VirtualKeyboard错误，以输入网站的字符

本文介绍了QML VirtualKeyboard错误，以输入网站的字符的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我目前正在修复目录系统上的一些错误。 这个系统有一个Webview面板和一个虚拟键盘。 这个系统是用QML，Javascript开发的和1％的C ++。 虚拟键盘在代码中有错误。 我输入了小写字母a，在网站文本框中它将显示为大写A。这发生在从A到Z的所有角色。 另一个问题是当我进入符号时，会出现奇怪的角色在文本框中。 以下来自事件面板的来源 QML 文件。 I currently repairing some bugs on the Directory System.This system has a Webview panel and also a virtual keyboard.This system was developed by using QML, Javascript and 1% of C++.The virtual keyboard has error in the codes. I entered lower case ''a'',in the website textbox it will appear as upper-case''A''. And this happen to all the character from A to Z.And another problem is when I entered Symbols, there will be weird character appearing in the textbox.Here below source from Event Panel QML file.//------------------------------------------------------// Keyboard//------------------------------------------------------WebKeyboardPad{ id: keyboard x: 0 y: event_panel.height + keyboard.height; anchors.horizontalCenter: parent.horizontalCenter onClicked: Globals.onKeyboardClicked(tag); onBackspace: Globals.onKeyboardBackspace(); opacity: 1 Behavior on y { id: behavior_nb_keyboard_y enabled: keyboard.isDragging NumberAnimation { duration: 300; } } Behavior on opacity { NumberAnimation { duration: 300; } }} 此来源来自 JavaScript 文件; This source is from a JavaScript file;function onKeyboardClicked(keyName){ home_main.onKeyboardClicked(keyName);}function onKeyboardBackspace(){ home_main.onKeyboardClicked("backspace");} 来自Main QML 文件 This from Main QML file//--------------------------------------------------- // Custom plugins //--------------------------------------------------- HardwareInfo { id: syshardware } function onKeyboardClicked(Keys) { myKeyboard.simulateKey(Keys); //Injected in main.cpp } function onKeyboardBackspace(KeyNavigation) { myKeyboard.simulateKey(KeyNavigation); //Injected in main.cpp //search_box.backspaceKey(); } 这里最后一个是C ++文件 keyboard.cpp 我更改了 keyboard.cpp 文件，但是当我尝试更改c ++代码时，结果仍然相同。 Here the last one is the C++ filekeyboard.cppI got change the keyboard.cpp file but when I try which the c++ code change, the result still the same.#include "keyboard.h"#include <qevent>#include <qkeyevent>#include <qapplication>Keyboard::Keyboard(QObject *parent) : QObject(parent){ theWidget = NULL;}void Keyboard::setWidget(QWidget* theWidget){ this->theWidget = theWidget;}void Keyboard::simulateKey(QString keyName){ Qt::Key keycode = getKeyCodeFromName(keyName);
