黑莓 - 自定义EditField中光标 [英] Blackberry - Custom EditField Cursor

问题描述

我创造我的BlackBerry项目一个搜索框，但它看起来像黑莓手机没有创建单行EditField中的API。我已经通过扩展BasicEditField并覆盖像布局和油漆的方法创建一个自定义字段。在油漆函数体，我画以get preferredWidth一个矩形（）和get preferredHeight（）。但光标在该EditField中默认的左上位置显示出来。谁能告诉我，我怎么能画光标在我的文字是什么？即，在EditField中通过调用的drawText（）中间。

I am creating a search box for my BlackBerry project, but it looks like BlackBerry doesn't have an API for creating a single line EditField. I have created a custom field by extending BasicEditField and overriding methods like layout and paint. In the paint function body, I am drawing a rectangle with getPreferredWidth() and getPreferredHeight(). But the cursor shows up at the default top-left position in the EditField. Can anybody tell me how I can draw the cursor where my text is? i.e. in the middle of EditField by calling drawText().

推荐答案

我没有得到你的问题，但。

I am not getting your question but.

1. 您可以创建单行编辑字段。

1. you can create single line edit field.

BasicEditField EDITFIELD =新BasicEditField（BasicEditField.NO_NEWLINE）;

BasicEditField editField = new BasicEditField(BasicEditField.NO_NEWLINE);

您可以设置光标的位置。

you can set cursor position.

editField.setCursorPosition（补偿）;

editField.setCursorPosition(offset);
