combobox with picklist keypress get record

[evansmith1]

Hello,

Using GWT 2.4 and Smart GWT 3.0. Most fun!

So I want to have a drop down that has formatted items, and I can get the record(s) of the item selected in the picklist that is the dropdown. I have the button click working fine, and the navigation with the keyboard. But when the enter key is clicked I can get the "enter" key, but can't seem to get the item from the pick list that was last selected. I have tried a few things.

here is my current code. Any ideas?

Evan

cbSearchOn = new ComboBoxItem();
cbSearchOn.setDisplayField("entvalue");
cbSearchOn.setSortField("entvalue");
cbSearchOn.setValueField("entvalue");
DataSource ds = DataSource.get("ravisearchon");
cbSearchOn.setOptionDataSource(ds);

// general settings
cbSearchOn.setHeight(28);
cbSearchOn.setWidth(450);
// comboBoxItemDiseases.setAnimationTime(3);
cbSearchOn.setCompleteOnTab(true);
// cbItem.setShowPickerIcon(true);
// TODO: tool tip on combo box does not format so well
cbSearchOn.setTooltip("<nobr>Start typing to reveal matches for your search.</nobr>");
// title to the left of combo box
cbSearchOn.setTitle("");

// initialize and fetch when the UI loads up
cbSearchOn.setAutoFetchData(true);

KeyUpHandler handler = new KeyUpHandler() {
@Override
public void onKeyUp(KeyUpEvent event) {
String strKeyName = event.getKeyName();
FormItem fi = event.getItem();
bindCurrentSearchOn(fi.getSelectedRecord());
if (strKeyName.equals("Enter")) {
fireEventsSearchOnResultsPage();
}
}
};
cbSearchOn.addKeyUpHandler(handler);

ListGridField entvalue = new ListGridField("entvalue");
entvalue.setCellFormatter(new CellFormatter() {
@Override
public String format(Object value, ListGridRecord record, int rowNum, int colNum) {
return record.getAttribute("entvalue") + getFieldType(record.getAttributeAsInt("entfieldskey")) ;
}
});

// The full record type is only "defined" when they select the item in the pick list
// It does not exist in the "box", only the value does at that point
CellClickHandler cellclickhandler = new CellClickHandler() {
@Override
public void onCellClick(CellClickEvent event) {
bindCurrentSearchOn(event.getRecord());
}
};

ListGrid pickListProperties = new ListGrid();
pickListProperties.addCellClickHandler(cellclickhandler);

KeyPressHandler keypresshandler = new KeyPressHandler() {
@Override
public void onKeyPress(KeyPressEvent event) {
String strKeyName = event.getKeyName();
if (strKeyName.equals("Enter")) {
// bindCurrentSearchOn(fi.getSelectedRecord());
}
}
};
pickListProperties.addKeyPressHandler((com.smartgwt.client.widgets.events.KeyPressHandler) keypresshandler);

cbSearchOn.setPickListProperties(pickListProperties);
// cbSearchOn.setPickListBaseStyle("");
cbSearchOn.setAnimatePickList(true);
cbSearchOn.setPickListFields(entvalue);

Hello,

So the basic thing I can't seem to do is get the record in the picklist from a combobox when a user hits enter.

I can get the "enter" event with a keypress handler on the combobox
KeyUpHandler handler = new KeyUpHandler() {
@Override
public void onKeyUp(KeyUpEvent event) {
String strKeyName = event.getKeyName();
if (strKeyName.equals("Enter")) {
// do something
}
}
};
combobox.addKeyUpHandler(handler);

So the do something should get the selected record for the combobox.
all the calls I have tried return null.
I can get the dropdown (my picklist) with items, use the arrows to move over one. It is highlighted. I hit return, and it is not inserted into the combobox. And I can't get the highlighted item regardless of what I try.

Thanks,
Evan

Perhaps the enter key is already on the string by the key up so it does not find a match.

Wondering what an "activated record" is, so a reference to this in the documentation.

Hello,

Still using Smart GWT 3.0 and GWT 2.4 in a firefox 7 browser.

So I have a ListGrid assigned to a combobox so my listgrid is my dropdown.

The following works great, for the click event and the mouse. However, I can't get the "enter" key press event. Though when a user hits enter in the listgrid the value is inserted into the combobox. So I can navigate with the arrow buttons int he list grid dropdown, and hit enter. But can't get the event occurring so I can see the "record" that is being selected in the grid before it is inserted into the combobox.

What am I missing.

Here is the click code which works, followed by the key press which does not fire.

Evan

CellClickHandler cellclickhandler = new CellClickHandler() {
@Override
public void onCellClick(CellClickEvent event) {
SC.logWarn(" cell click pressed in picklist");
bindCurrentSearchOn(event.getRecord());
}
};
pickListProperties.addCellClickHandler(cellclickhandler);
// should also turn off keyboard
pickListProperties.setCanEdit(false);
// should turn off keyboard
pickListProperties.setCanFocus(false);


and my keypress broken handler
KeyPressHandler keypresshandler = new KeyPressHandler() {
@Override
public void onKeyPress(KeyPressEvent event) {
// SC.say("keypress in picklist");
SC.logWarn(event.getKeyName() + " pressed in picklist");
}
};
pickListProperties.addKeyPressHandler(keypresshandler);

I guess what I want is the addcell keypress handler, but I don't see that.

Based on other threads I found this method. Looks promising.
However, though I made the setting the cellClickHandler is not called when I hit enter in my picklist (ListGrid).

Evan

CellClickHandler cellclickhandler = new CellClickHandler() {
@Override
public void onCellClick(CellClickEvent event) {
SC.logWarn(" cell click pressed in picklist");
bindCurrentSearchOn(event.getRecord());
}
};
pickListProperties.addCellClickHandler(cellclickhandler);


pickListProperties.setGenerateClickOnEnter(true);
