I'm trying to submit an small form either by clicking the submit button or by
hitting return when the cursor is in the textfield (everyone should know this
behaviour from forms in HTML).
The important parts of my code (it's within a class):
// ...
construct : function() {
this.create();
},
members: {
create : function() {
// creating the grid layout and so on...
paneSearch_groupboxSearch_textfieldClient = new qx.ui.form.TextField;
with( paneSearch_groupboxSearch_textfieldClient ) {
setLiveUpdate( true );
addEventListener( "keyup", this.checkSubmitSearchBillings );
}
paneSearch_groupboxSearch_gridLayout.add(
paneSearch_groupboxSearch_textfieldClient, 1, 4 );
paneSearch_groupboxSearch_buttonSearch = new qx.ui.form.Button("Search");
with( paneSearch_groupboxSearch_buttonSearch ) {
addEventListener( "execute", this.searchBillings );
}
paneSearch_groupboxSearch_gridLayout.add(
paneSearch_groupboxSearch_buttonSearch, 3, 4 );
// adding elements to document...
},
searchBillings : function() {
// do something
},
checkSubmitSearchBillings : function( keyEvent ) {
if( keyEvent.getIdentifier()=="Enter" ) {
this.searchBillings();
}
}
}
// destrcutor and closing the class
There are no error while loading the page but if I hit the return key in the
textfield, there is only the error message:
ERROR: qx.event.handler.EventHandler[60]: Failed to dispatch key event:
TypeError - this.searchBillings is not a function
Clicking the button works fine and there is also no error if I use
"this.searchBillings" as event function for the textfield.
Anybody there with an idea and/or solution for this problem? I can't find the
problem. One solution might be to copy the code of searchBillings into
checkSubmitSearchBillings, but that's no good programming as you might agree
with me.
Best regards,
Christian
