Abstract
本发明涉及一种动态生成FORM页面的方法，应用于利用DELPHI语言开发的应用程序，是针对其界面生成中实现所有子窗口FORM页面的一种法，其包括动态定义、TAB页面事件、及动态调用各页面技术。本发明的动态生成FORM页面的方法，实现了DELPHI应用程序方面的一种主子窗口的创新，其方法可适用于任何DELPHI语言开发的应用程序。
Description
技术领域
本发明涉及计算机语言技术领域，尤其是在创建子窗体方面，能够动态生成多页面窗体，实际解决子窗体多页面显示的一种方法。
背景技术
传统的子窗体显示是单体显示在主窗口，但不能排列显示而且在窗体只能一次显示一个子窗体，在应用程序操作过程中不方便操作人员进行操作。
发明内容
本发明的目的在于利用DELPI语言本身的创建类功能，实现动态的子窗体附加在TAB页面中，主要解决了窗体在动态生成时，其属性及其事件在关闭窗体时能及时释放计算机内存，而再次显示是不再重新创建其无效的窗体。
为达到上述目点，本发明采用的方法是：通过动态创建子窗体、设置其属性、写入数据库及读取数据库中数据。
计算机首先动态创建FORM窗体，定义其窗体为所显示窗体类，其创建的窗体的句柄为TAB页句柄，设置其FORM窗体的显示属性为无窗休属生，设置其Parent属性为动态的TAB，设置显示的TAB的CAPTION容，设置其显示的ActivePageIndex的值，并把其值写入数据库中，以备重新谈取时直接显示其ActivePageIndex属性。
当操作人员关闭其动态创建的FORM的页面时，则需要释放其暂用的计算机内存，由于无法确定其释放的页面ActivePageIndex属性，则需要通过计算ActivePageIndex的值，通过循环读取其页中已有的FORM属性与需要关闭的属性进比较，如相等则关闭其页面并释放所占有的内存。
Claims (2)
1.一种动态生成FORM页面的方法，由其页面定义、页面调用、页面显示及TAB页的事件生成，其特征在于：
所述方法由其页面定义、页面调用、页面显示及TAB页事件组成。
页面定义，则由DEPHI语言创建动态的页面句柄，设置页面的属性及其事件。
2.根据权利要求1所述的方法，其特征在于：所述的动态创建的页面在于在主窗口显示所定义的子窗口页面，设置其属性。
