我具有以下格式，并且我想根据其他列的值来更改列的背景色；

I have following form and I want to change the background color of a column, based on the values of other columns;

在橙色列中，我希望单元格颜色是红色，绿色和红色的RGB组合，而不是显示橙色背景. 颜色属性"部分下的蓝色字段.

In the orange columns, instead of displaying orange background, I want the cell color to be the RGB combo of Red, Green & Blue fields under COLOR ATTRIBUTES section.

推荐答案

比方说，您需要更改其背景的控件名为FirstFieldControl.将其AutoDeclaration属性设置为Yes，将BackgroundColor属性设置为Window background.

Let's say that the control the background of which you need to change is named FirstFieldControl. Set its AutoDeclaration property to Yes and BackgroundColor to Window background.

现在，您需要在数据源上覆盖displayOption方法，例如:

Now you need to override the displayOption method on your datasource, e.g.:

public void displayOption(Common _record, FormRowDisplayOption _options) { YourTable yourTable = _record; int color; ; switch (yourTable.Name) { case 'Red' : color = WINAPI::rgbCon2int([255, 0, 0]); break; case 'Green' : color = WINAPI::rgbCon2int([0, 255, 0]); break; case 'Blue' : color = WINAPI::rgbCon2int([0, 0, 255]); break; } if (color) { _options.backColor(color); _options.affectedElementsByControl(FirstFieldControl.id()); } else { super(_record, _options); } }

这只是一个例子，可以给您一个想法-不要复制粘贴:)

This is just an example to give you an idea - don't copy-paste :)

将颜色值存储在表中比较容易，然后代码会更好.

It's easier to store the color value in the table, then the code will be much nicer.

PS .如果您要更改颜色运行时，则可能需要使用以下代码来刷新记录:

P.S. If you're changing the colors run-time you might need to use the following piece of code to refresh the record:

yourTable_ds.clearDisplayOption(yourTable); yourTable_ds.refresh();
