What is the best way to format log lines in a GWT custom logging section?

In GWT, a personalized logging area can be created by implementing a HasWidgetsLogHandler. In my situation, I am using a VerticalPanel. However, the logging output is too wide and distorts the rest of the page. How can I wrap the lines?

Each log entry adds an HTML element through the HasWidgetsLogHandler. I attempted to style the individual elements in UiBinder without success:

<ui:style>
  @external gwt-HTML;
  .gwt-HTML {
    white-space: normal;
  }
</ui:style>

Even trying to add overflow: hidden—which would have been a less ideal solution—had no impact.

Any guidance on this matter would be greatly appreciated.

Answer №1

A VerticalPanel is structured as an HTML table. While it can be utilized, my recommendation would lean towards using a FlowPanel instead.

Within a FlowPanel, you have the capability to adjust the following attributes:

white-space: normal;
word-wrap: break-word; 

The CSS3 feature word-wrap is supported by numerous browsers: http://caniuse.com/wordwrap. It allows long words to be broken after each character. For browsers lacking support, you may need to include overflow: hidden. (Alternatively, consider setting a fixed width in conjunction with overflow: auto.)

If utilizing a VerticalPanel is an absolute necessity, refer to Word-wrap in an HTML table (word-wrap must be set on the <td>).
