Description

背景技术
软键盘是一种虚拟键盘，通常是由软件工具制作而成。软键盘可以代替传统物理键盘作为输入信号的工具。在很多场合下，为了模拟传统物理键盘的外观以及功能，软键盘通常采用矩形设计，并设置了字母、数字或者其他符号或功能按键。其常用功能包括：输入数字、输入大小写字母、输入常用符号、输入箭头、退格、回车、空格符号等。
但是，在某些特殊的领域中，例如在操作机器人示教器软件时，经常遇到只需要输入数字的情况。在这种情况下，字母以及某些字符的信号对于机器人示教器软件来说是无效的字符。对于操作者来说，如果没有相应的提示，可能会输入除数字以外的其他字符，例如字母字符，这样就导致软件运行时因为接收到无效的字符而出现错误并报警，影响了操作者在操作示教器软件时的效率。

具体实施方式
本发明实施例提供了一种数据输入方法、装置及设备，用于在特定情况下限制输入的字符类型，降低了输入数据时的出错概率，提高工作效率
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明实施例中，系统在生成并显示软键盘后，用户通过软键盘输入字符进行操作，由于软键盘在设计时由三种不同类型的字符组成，输入不同类型的字符在进行相关后续操作时的方法和步骤不同，下面就三种不同的字符处理方法进行描述：
请参阅图2，图2是本发明实施例的一种数据输入方法的一个实施例示意图。其中，图2所示的实施例是当输入的字符类型是数字字符时的处理方法。该方法可适用于机器人、机器人示教器、数控机床、计算机等用户终端。如图2所示，该方法可以包括：
步骤201、系统生成并显示软键盘；
系统通过应用软件编辑并生成软键盘。在实际运用中，系统可以通过应用Qt框架生成软键盘，也可以利用Java语言生成软键盘，还可以利用MFC(Microsoft Foundation Classes，微软基础类库)或其他程序、框架、编程语言生成软键盘，此处不做具体限定。
下面以利用Qt生成软键盘为例进行说明：系统通过Qt生成软键盘，具体步骤如下：利用Qt中的QPushbutton类控件创建所有按键，设置尺寸属性， 并利用QVBoxLayout类控件和QHBoxLayout类控件对按键的布局进行设置。然后使用DOM(Document Object Model，文档对象模型)方式读取配置文件，根据配置文件确定对应按键显示的内容，并设置按键对应的键值及其他属性，键值用于确定按键被点击时向当前焦点窗口发送的值。之后用Qt的信号与槽机制，将按键的keyClick信号和keyPress槽函数关联起来，当按键被按下时就发送keyClick信号，keyClick信号触发keyPress槽函数，在keyPress槽函数中通过调用sendKey函数发送正确的键值，从而实现字符输入。在实际应用中，软键盘可以包括数字按键、负号按键以及点号按键。其中，数字按键可以是由0至9的十进制数字组成的按键，这种设置方法符合当前常用的数字输入方式，适用性较好。负号按键对应数学中的负号，用于区分数值的正负值。点号按键对应数学中的小数点，在表示非整数时可以用到。
在生成软键盘步骤完成后，系统会将软键盘显示供用户使用，具体软键盘的一种设计示意图请参阅图1，在实际应用中软键盘的设计也可以有其他形式，此处不作具体限定。
步骤202、系统通过软键盘接收输入信号；
用户通过软键盘点击相关按键发出信号，系统接收到这些信号会对信号进行分析，根据分析得到的信号对应的字符作出不同的处理，例如当接收到数字按键输入的信号时，系统会显示该数字按键对应的字符。
步骤203、系统确定输入的字符为数字字符；
当用户点击数字按键时，系统会接收到按下数字按键时对应的信号，系统对信号进行分析得到数字按键的对应数字字符，从而进行相关处理，例如此时接收到数字按键输入的信号，则会显示该数字按键对应的字符，假如到数字1的按键信号，则会显示数字1的字符。
步骤204、系统判断显示框中是否有负号字符；
当系统确定字符类型为数字字符后，会首先判断字符显示框中有没有负号字符，即判断用户在先有没有输入负号字符，这里的负号字符即用于区别数字正值以及负值的字符，与数学上的负号对应。若系统判断显示框中存在负号字符，则执行步骤205，若系统判断显示框中不存在符号字符，则执行步骤207。
步骤205、系统判断光标是否在负号字符之前；
系统判断光标是否在负号字符之前，光标的位置标识字符输入后在字符显 示框中的位置，光标在负号字符之前表示输入的字符会在负号字符之前的字符位。
在实际应用中，光标可以是一条闪烁的竖线，也可以是其他的形式，只要能起到提示用户输入字符的位置即可，此处不作具体限定。
需要说明的是，字符显示框一般被设置成按照从左至右顺序显示输入的字符，光标在符号之前表示光标在负号字符左边的字符位，字符显示框也可以有其他设置方式，此处不作具体限定。
若系统判断光标在负号字符之前的字符位，则执行步骤206，若系统判断光标不在负号字符之前的字符位，则执行步骤207。
步骤206、系统过滤字符；
当系统判断光标在负号字符之前的字符位，系统会判断此时的输入字符无效，不符合操作指令规定，所以系统会把字符信号过滤，不处理无效的字符信号。
步骤207、系统在光标处插入数字字符；
当系统判断光标在负号字符之后的字符位，此时输入的字符是有效的，相关的设备可以根据相关的字符对应的指令工作，此时系统会在光标处插入字符。
本实施例是针对当输入的是由数字按键生成的数字字符时的处理步骤，由于数学上的限制，输入数字字符不能出现在负号字符之前，所以本实施例能够保证输入的数字字符的有效性。
二、输入的字符类型是负号字符时的处理方法。
请参阅图3，其中，图3所示的实施例是当输入的字符类型是负号字符时的处理方法。如图3所示，该方法可以包括：
本发明实施例中步骤301与步骤201相同，此处不再赘述。
步骤302、系统通过软键盘接收输入信号；
用户通过软键盘点击相关按键发出信号，系统接收到这些信号会对信号进行分析，根据分析得到的信号对应的字符作出不同的处理，例如当接收到负号按键输入的信号时，系统会显示该负号按键对应的负号字符。
步骤303、系统确定输入的字符为负号字符；
当用户点击负号按键时，系统会接收到负号按键对应的信号，系统对信号 进行分析得到负号按键的对应负号字符，从而进行相关处理，例如此时接收到负号按键输入的信号，则会显示该负号按键对应的字符，即显示“-”字符。
步骤304、系统判断字符显示框中是否有负号字符；
当系统确定字符类型为负号字符后，会判断字符显示框中有没有负号字符，即判断用户在先有没有输入负号字符。若系统判断字符显示框中存在负号字符，说明在先已经输入过负号字符，则执行步骤305，若系统判断显示框中不存在符号字符，则执行步骤307。
步骤305、系统过滤字符；
当系统判断字符显示框中在先已经存在负号字符，系统会过滤在后用户输入的负号字符，这种方法保证了字符显示框中只有一个负号字符。
步骤306、系统将光标移动至字符显示框的第一个字符位；
当系统判断字符显示框中不存在负号字符，则会把光标移动至字符显示框的第一个字符位。
需要说明的是，通常由于字符显示框被设置成按照从左至右顺序显示字符，字符显示框的第一个字符位表示在字符显示框最左面的字符位。字符显示框也可以有其他设置方式，此处不作具体限定。
步骤307、系统在光标处插入负号字符；
系统在光标初插入负号字符，由于在步骤306中，系统把光标移动至字符显示框的第一个字符位，此时在光标处插入负号字符，使得负号字符总会在字符显示框的第一个字符位。
本实施例是针对当输入的是由负号按键生成的负号字符时的处理步骤，由于在数学上的限制，数字字符不会在负号字符之前，所以当需要输入负号字符时，系统总是会将负号字符安排在最前的位置确保之后输入的字符正确，本实施例能够保证输入的负号字符的有效性。
三、输入的字符类型是点号字符时的处理方法。
请参阅图4，其中，图4所示的实施例是当输入的字符类型是点号字符时的处理方法。如图4所示，该方法可以包括：
本发明实施例中步骤401与步骤201相同，此处不再赘述。
步骤402、系统通过软键盘接收输入信号；
用户通过软键盘点击相关按键发出信号，系统接收到这些信号会对信号进 行分析，根据分析得到的信号对应的字符作出不同的处理，例如当接收到点号按键输入的信号时，系统会显示该点号按键对应的点号字符，此处点号字符即数学上的小数点，用于表示非整数的输入。
步骤403、系统确定输入的字符为点号字符；
当用户点击点号按键时，系统会接收到按下点号按键时对应的信号，系统对信号进行分析得到点号按键的对应点号字符，从而进行相关处理，例如此时接收到点号按键输入的信号，则会显示该点号按键对应的字符，即显示“.”字符。
步骤404、系统判断字符显示框中是否有负号字符；
当系统确定字符类型为点号字符后，会判断字符显示框中有没有负号字符，即判断用户在先有没有输入负号字符。若系统判断字符显示框中存在负号字符，说明在先已经输入过负号字符，则执行步骤405，若系统判断显示框中不存在符号字符，则执行步骤406。
步骤405、系统判断光标是否在负号字符之前；
系统判断光标是否在负号字符之前，由于光标的位置对应了相关字符输入后在字符显示框中的位置，所以光标在负号字符之前表示输入的字符会在负号字符之前的字符位。
若系统判断光标在负号字符之前的字符位，则执行步骤407，若系统判断光标不在负号字符之前的字符位，则执行步骤406。
步骤406、系统判断字符显示框中是否有点号字符；
系统判断字符显示框中是否在先已经有点号字符，若有，则执行步骤407，若没有，则执行步骤408。
步骤407、系统过滤点号字符；
当系统判断光标在负号字符之前或字符显示框中在先有点号字符，系统会过滤用户在后输入的点号字符，这种方法保证了字符显示框中只有一个点号字符，且如果有负号字符，在后输入的点号字符会在负号字符之后的字符位。
步骤408、系统在光标处插入点号字符；
当系统判断字符输入框中没有点号字符，则说明在先用户没有输入点号字符，此时系统会在字符显示框中的光标处插入点号字符，结合步骤407，保证了最多只能输入一个点号字符。
本实施例是针对当输入的是由点号按键生成的点号字符时的处理步骤，由于在数学上的限制，当需要输入点号字符表示非整数时，输入的点号字符必须在负号字符之后，而且只能存在一个点号。本实施例能够保证输入的点号字符的有效性。
