GWT CustomScrollPanel Beispiel

Question

Ich habe herausgefunden, über GWT CustomScrollPanel und wie Sie die Bildlaufleiste anpassen können, aber ich finde keine Beispiele oder wie Sie es einrichten. Gibt es Beispiele, die benutzerdefinierte Scrollbalken verwenden?

Answer 1

So würden Sie die nativen Bildlaufleisten anpassen, Sie könnten jedoch auch eigene Bildlaufleistenklassen entwickeln, die VerticalScrollbar und HorizontalScrollbar implementieren und wesentlich anpassbarer sind.

Ressource (Stil) Definitionen:

public class ScrollResourcesContainer { 

    public interface ScrollPanelResources extends CustomScrollPanel.Resources 
    { 
     @Override 
     @Source({ "ScrollPanel.css", CustomScrollPanel.Style.DEFAULT_CSS }) 
     CustomScrollPanel.Style customScrollPanelStyle(); 
    } 

    public interface HorizontalResources extends NativeHorizontalScrollbar.Resources 
    { 
     @Override 
     @Source({ "HorizontalScrollbar.css", NativeHorizontalScrollbar.StyleTransparant.DEFAULT_CSS }) 
     NativeHorizontalScrollbar.Style nativeHorizontalScrollbarStyle(); 
    } 

    public interface VerticalResources extends NativeVerticalScrollbar.Resources 
    { 
     @Override 
     @Source({ "VerticalScrollbar.css", NativeVerticalScrollbar.StyleTransparant.DEFAULT_CSS }) 
     NativeVerticalScrollbar.Style nativeVerticalScrollbarStyle(); 
    } 
} 

Nutzung über CustomScrollPanel:

CustomScrollPanel csp = new CustomScrollPanel((ScrollResourcesContainer.ScrollPanelResources) GWT.create(ScrollResourcesContainer.ScrollPanelResources.class)); 
    csp.setHorizontalScrollbar(new NativeHorizontalScrollbar((HorizontalResources) GWT.create(HorizontalResources.class)), 
    AbstractNativeScrollbar.getNativeScrollbarHeight()); 
    csp.setVerticalScrollbar(new NativeVerticalScrollbar((VerticalResources) GWT.create(VerticalResources.class)), 
    AbstractNativeScrollbar.getNativeScrollbarWidth()); 

Answer 2

Um die schlanken Bildlaufleisten für vertikale Bildlaufleiste in gwt zu erhalten, müssen Sie in den verticalScrollBar folgenden Code hinzuzufügen. css. Welche funktioniert nicht für IE wie Google Mail.

/* Turn on a 16x16 scrollbar */ 
::-webkit-scrollbar { 
    width: 16px; 
    height: 16px; 
} 

/* Turn on single button up on top, and down on bottom */ 
::-webkit-scrollbar-button:start:decrement, 
::-webkit-scrollbar-button:end:increment { 
    display: block; 
} 

/* Turn off the down area up on top, and up area on bottom */ 
::-webkit-scrollbar-button:vertical:start:increment, 
::-webkit-scrollbar-button:vertical:end:decrement { 
    display: none; 
} 

/* Place The scroll down button at the bottom */ 
::-webkit-scrollbar-button:end:increment { 
    background-image: url(images/scroll_cntrl_dwn.png); 
} 

/* Place The scroll up button at the up */ 
::-webkit-scrollbar-button:start:decrement { 
    background-image: url(images/scroll_cntrl_up.png); 
} 

/* Top area above thumb and below up button */ 
::-webkit-scrollbar-track-piece:vertical:start { 
    background-image: url(images/scroll_gutter_top.png), url(images/scroll_gutter_mid.png); 
    background-repeat: no-repeat, repeat-y; 
} 

/* Bottom area below thumb and down button */ 
::-webkit-scrollbar-track-piece:vertical:end { 
    background-image: url(images/scroll_gutter_btm.png), url(images/scroll_gutter_mid.png); 
    background-repeat: no-repeat, repeat-y; 
    background-position: bottom left, 0 0; 
} 

/* The thumb itself */ 
::-webkit-scrollbar-thumb:vertical { 
    height: 56px; 
    -webkit-border-image: url(images/scroll_thumb.png) 8 0 8 0 stretch stretch; 
    border-width: 8 0 8 0; 
}

Wenn jemand in mit dem CSS sowohl vertikal/horizontal interessiert ist, ist es das, was ich verwende.

HorizontalScrollbar.css

.nativeHorizontalScrollbar::-webkit-scrollbar-button:end:increment

}
