縦スクロールについて

こんにちは、初めまして。


初投稿させていただきます。


掲題の件ですが、

トラックをクリック時に、１ページ分移動します。

トラックの一番下を長押しし、一番下へカーソルを移動した後で、

トラックを再クリック時に、2ページ分、3ページ分など移動しまう。

リファレンスを参照してもスクロールがらみの制御方法が不明で

手詰まり状態となっています。


どなたか情報をお持ちの方がいらっしゃいましたら

情報を共有いただけませんでしょうか？


以上です。


よろしくお願いいたします。

Correct answer kglad

i have used datagrid ,ComboBox,Canvas

the problem was discovered


create a new fla, add a datagrid to the library and the code below.  do you see any problem?

import fl.controls.DataGrid;

import fl.controls.ScrollPolicy;

import fl.data.DataProvider;

var i:uint;

var totalRows:uint = 100;

var dp:DataProvider = new DataProvider();

for (i = 0; i < totalRows; i++) {

    dp.addItem({col1:i, col2:Math.round(10*Math.random())});

}

var dg:DataGrid = new DataGrid();

dg.setSize(200, 300);

dg.columns = ["col1", "col2"];

dg.dataProvider = dp;

addChild(dg);

dg.verticalPageScrollSize=dg.height-dg.rowHeight;

the ms translator made a mess of your message and google translate is not much better.

so, i don't know what you're asking but it seems to be a question about textfield scrolling.  if true, check the textfield's scrollV, maxScrollV and bottomScrollV properties and check all the getXXX() methods of the textfield.

thank you for the answer

sorry for my weak English

when I click the track of the scrollbar,the datagrid 1 page scroll

but after i gave the track a long click,

i click the track once more, the datagrid 2 page or 3 page scroll

after a long click ,  when i click the track once more ,i want the datagrid also 1 page scroll

but i don't know how to do

use the verticalPageScrollSize to set the number of pixels you want your datagrid to scroll.  for most situations, picking a number less than or equal to the datagrid's height minus its rowHeight is what you'll want:

dg.verticalPageScrollSize=dg.height-dg.rowHeight;
