Hello! I'm new in GWT development and need some help. I use GWT 2.0
and want define once some constant. For example, I need to define
mainColor = #rrggbb and want use it in various places, like CSS,
MyWidget, MyWidget.ui.xml, etc.
I read about CssResource, read about working with CSS docs, but can't
understand, what rule is the best.
Now my idea realized like this:
GlobalRes.java:
-----------------------------------------------------------------------------------------
public class GlobalRes {
static public int gap = 10;
static public String getGap() {
return gap + "px";
}
static public String getDoubleGap() {
return (gap * 2) + "px";
}
static public String mainColor() {
return "#e6dbcf";
}
}
-----------------------------------------------------------------------------------------
ControlPanel.css:
-----------------------------------------------------------------------------------------
@eval gap admin.client.GlobalRes.getGap();
@eval gap2 admin.client.GlobalRes.getDoubleGap();
@eval mainColor admin.client.GlobalRes.mainColor();
body {
padding: gap;
}
.header {
background: mainColor;
margin-bottom: gap2;
}
-----------------------------------------------------------------------------------------
I can use variables like 'gap' and 'gap2' in many places. If I prefer,
I can change this gap in 1 place (GlobalRes.java) and value changed in
100 places. But it has bottleneck. First lines in ControlPanel.css I
must repeat in other CSS-files.
There is my question: I miss some docs and my code is little stupid?
Anyone can help me?
Thanks for any answer,
Pavel.
