9. Multi-page component
68) Q: I think C + + Builder component template management well, in the template by clicking the page you can switch between the various pages in C + + Builder in to achieve what should I do ?
A: We can be achieved with multi-page components, its benefits is that you can in a limited space to store as much information, and facilitate the information classified. Take for instance the template components, then the small screen in place of the hundreds of components, and does not look messy, which are multi-page component of the credit.
If the form you want to place a large number of components, and grouping these components is used, then consider using multi-page components. This would allow a more concise form.澶氶〉缁勪欢鏃㈡湁澶氶〉鐨勭壒鎬э紝鍙堟槸涓?釜瀹瑰櫒缁勪欢锛屽畠灏卞儚绐椾綋涓?牱鍙互鍖呭惈鍏朵粬鐨勭粍浠躲?
C + + Builder provides several features similar to multi-page components, which are: Win32 page in the TabControl, PageControl components, Win31 page TabSet and TabbedNoteBook components. From their different page where you can know that the first two components are used in 32-bit system components, in terms of performance and style, the two components are more suitable for Windows 95 and above board in this used. Last two components is the favorite Windows 3.1-style user reservations, in fact, we can only use the first two components.
69) Q: TabControl component and PageControl components they simply look exactly the same?
A: At first glance, these two components almost certainly, we can operate below illustrates this point.
(1) in the form to place these two components, by modifying the Height and Width properties set them the same size.

The difference is that with the TabControl component, you can click the page to switch between pages. Click the page to switch pages as well as in selected components of the PageControl. If you want to select a page, you can first click the page to switch to the page, then click the page on it.

They look exactly the same way.

Obviously, if you need to display each page different components, then certainly not qualified for such work TabControl. Because every time you change page, you must update the page with the code template, which in C + + Builder is not a good idea.濡傛灉姣忎釜椤垫墍鏄剧ず鐨勭粍浠剁浉鍚屽彧鏄唴瀹规湁鍙樺寲锛岄偅涔堜娇鐢═abControl浼氭洿鍔犲悎閫傦紝鍥犱负瀹冩秷鑰楃殑绯荤粺璧勬簮姣旇緝灏戙?

Tabs property used to set the page number and title, in the design is to use a string editor to achieve.
72) Q: TabControl control which of the more important events?
A: TabControl has two more important events OnChange and OnChanging. Whenever the page is selected OnChange event occurs after this time can determine which pages TabIndex property is selected, and then respond to the action taken.
OnChanging incident occurred just before the page is selected, that is just a page before switching to another page. This event allows us to switch the page to take certain actions before, for example, not set in until certain conditions are not allowed to leave this page.
In fact, before these two events we have studied in detail, not illustrated here.
73) Q: PageControl component seems more powerful than the TabControl component, which is how to use it?
A: Compared with the TabControl, PageControl indeed more powerful component features, but not complicated. PageControl涓殑姣忎竴涓〉閮芥槸涓?釜TTabSheet缁勪欢锛岃繖涓粍浠跺疄闄呬笂鏄竴涓鍣紝浣犲彲浠ュ湪涓婇潰鏀剧疆鍚勭鎺т欢銆?Each TTabSheet component has its own attributes.
