SearchField Suggest All When Empty #219
Description
Suggesting an enhancement.
I am using the SearchField and would like to know if there is a way to get the suggestions to appear with a user text of an empty string?
In my application a long list of options is available but I would not expect a user to know which option they would like before they start typing in all situations. Rather than trying every letter of the alphabet first, it would be nice if while focused/typing cursor, the suggestions popup is visible with whatever results the suggestion provider gives for the empty string in the typing area.
Could a property be added for this? Something like "suggestWhenBlank". Here are where I believe it would need to be to affect this functionality. Not all blank text checks need it.
around line 229 of SearchField
editor.textProperty().addListener(it -> {
if (!committing) {
if (StringUtils.isNotBlank(editor.getText()) || suggestWhenBlank.get()) {
searchService.restart();
} else {
update(null);
}
}
});
around line 640 of SearchField
if (!isCancelled() && (StringUtils.isNotBlank(searchText) || suggestWhenBlank.get())) {
around line 50 of SearchFieldPopup
if ((!searchField.getSuggestions().isEmpty() || searchField.getPlaceholder() != null) && (StringUtils.isNotBlank(searchField.getEditor().getText()) || searchField.suggestWhenBlank.get())) {
along with this comes the behaviour of showing results before typing has started and for that I would change around line 158
if (!editor.isFocused()) {
// Add the current text to the history if the editor lost focus.
if (isAddingItemToHistoryOnFocusLost()) {
addToHistory(editor.getText());
}
commit();
if (getSelectedItem() == null) {
editor.setText("");
} else {
invokeCommitHandler();
}
}
else if (suggestWhenBlank.get() || StringUtils.isNotBlank(editor.getText())) {
searchService.restart();
}
