QCalendar error in 2.0
Sat, 03/27/2010 - 21:44
I have started development, using QCubed 2.0 and found a problem with QCalendar. In the following code, I get the error: "strlen() expects parameter 1 to be string" at line 170 of QControlBase.class.php.
$this->dtxComtCalendar = new QDateTimeTextBox($this);
$this->calComtExpDate = new QCalendar($this, $this->dtxComtCalendar);The call stack looks like this:
#0 (): QcodoHandleError()
#1 C:\wamp\www\htw2\includes\qcubed\_core\base_controls\QControlBase.class.php(170): strlen()
#2 C:\wamp\www\htw2\includes\qcubed\_core\base_controls\QTextBoxBase.class.php(64): QControlBase->__construct()
#3 C:\wamp\www\htw2\wla\customers_edit.php(413): QTextBoxBase->__construct()
#4 C:\wamp\www\htw2\includes\qcubed\_core\base_controls\QFormBase.class.php(294): CustomersEditForm->Form_Create()
#5 C:\wamp\www\htw2\wla\customers_edit.php(714): QFormBase::Run()The problem is in creating the new QCalendar control.
Running the Examples Date and DateTime-based QControls fails completely.
This code works without exception in 1.1.1.
Looks like the new control may include its own QTextBox instead of needing one supplied. I wonder if there's a way to keep this backwards compatible.
If not, we need to update the example (and any codegen templates that utilize it) to use the new syntax.
VexedPanda, after some testing, I see you are correct. It's actually very much simpler now. It's no longer necessary to create a QDateTimeTextBox and then a QCalendar attached to it. Simply create the QCalendar as the control and you're done.
I'll look into adding the capability to add more options to it.
Thank you!
I created a ticket for this:
http://trac.qcu.be/projects/qcubed/ticket/539
However, the examples work properly on my system, are you sure you updated your examples as well?
The new QCalendar seems to work without any problems. I think all that is needed is update of examples documentation for 2.0.
can you indicate where we should update? I noticed that examples are working fine here...?
Kristof:
In 1.1.1 it's necessary to create a QDateTimeTextBox and then attach QCalendar to it. In 2.0, all I needed was the QCalendar.
In Examples, when I take the Date and Date Time-based QControls, I get the following error:
"Trying to get property of non-object"
at line 53 of datetime.php.
$this->btnCalendar->ActionParameter = $this->dtxCalendar->ControlId;Basically, it seems like btnCalendar and btnCalendarPopup can be eliminated.
Thanks,

Kristof, I've created several enhancements to the QCalendar control. Ive added the following options:
minDate, maxDate, defaultDate, firstDay, gotoCurrent, IsRTL, numberOfMonths, and autoSize.
There are quite a few other options available, which I have not given much attention. However, if anyone wants any of them added, I'll be happy to do so.
Please have a look at ticket# 539 for the details. The new QCalendar is attached to that ticket.
Thanks,
LaCeja
I'm sorry to beat what might be a dead horse on this, but would you be able to clarify the backwards-compatibility issues on this? Creating a QDateTimeTextBox/QCalendar combination does not seem to work at all in 2.0, but, as LaCeja indicates, you only need the calendar piece. I'm assuming that when I port my 1.1 application to 2.0, I will run into problems on this? I don't have calendars lying all over the place, but still it's something I'd like to keep in the back of my mind.
Thanks guys!
I believe the QDateTimeTextBox QCalendar stuff was fixed in either 2.0.1 or in SVN (which will be released as 2.0.2). As for backwards compatibility, I believe the existing controls should be backwards compatible (and if they are not, we should fix that). There are also new jQuery-based controls that do have different syntax, but you can choose which to use.
