Is there a way to load WText widget dynamically with WLink and WResource like it is done in WImage? It is needed for slowly generated text at server side.
Hello Igor,
apologies for the delay.
There is no way to directly use WText as you can do with WImage for example. Depending on how you handle this data:
WMemoryResource may be what you are looking for.WStreamResource, if spooling it to a file is fine. But that may not be sufficient for your use-caseIf this doesn't quite cover it, and you are looking more of a tail -f {file}-like approach, you want to have a WContainerWidget (or WTemplate) to which WText items are appended. To ensure that the server is able to push data to the client, take a look at WApplication::enableUpdates().
I hope that helps you along, and if not, please let me know.
I have found a workaround for this issue after some time:
TextResource class that inherits from WResource and established a WLink to it.WWidget containing a WImage that references the link. The purpose of this link is to initiate the download of text content instead of an image.TextResource to the setText method of the WText widget that needs to display the text.This method works because Wt attempts to load all images, regardless of whether they are displayable or not.
