    Simple TIP: AlwaysOnTop feature for windows and forms

    in Components and Code Samples

    Posted

    I think that was all... It could be the following: be sure that you are writing code within OnBeforerender of Ext.Window, not of Ext.form.FormPanel...

     

    Are you sure that this (taken from AlwaysOnTop.js)

    Ext.application({
			name: 'AlwaysOnTopDemo',
			controllers: [
				'Ext.ux.util.AlwaysOnTop'
			]
});

    is the proper way to get the controller? I inspected my generated page source and this is the order in which the scripts are loaded:

    ...
<script src="ext-4.1.1a/ext-all.js"></script>
<script src="ext-4.1.1a/uni-0.93.0.995/ext-sync-min.js"></script>
<script type="text/javascript">

Ext.Loader.setConfig({enabled:true,paths:{"Ext.uni":"ext-4.1.1a/uni-0.93.0.995"}});

</script>

<link rel=stylesheet href="ext-4.1.1a/uni-0.93.0.995/css/uni-xtheme-common.css" />
<link rel=stylesheet href="ext-4.1.1a/uni-0.93.0.995/css/uni-xtheme-blue.css" />
<script src="/AlwaysOnTop.js"></script>
<script src="ext-4.1.1a/uni-0.93.0.995/ext-treenode-plugin.js"></script>
<script src="ext-4.1.1a/uni-0.93.0.995/unicanvas-min.js"></script>
<script src="ext-4.1.1a/examples/ux/form/MultiSelect.js"></script>
<script src="ext-4.1.1a/uni-0.93.0.995/ext-unigui-min.js"></script>
...

    maybe the alwaysontop controller gets lost :D

    Simple TIP: AlwaysOnTop feature for windows and forms

    in Components and Code Samples

    Posted

    I tried to create another project using this workaround for AlwaysOnTop, but I failed.

    Here is what I did:

    • Copy-Paste AlwaysOnTop.js in the project root
    • ServerModule->CustomFiles="AlwaysOnTop.js"
    • Form->TUniClientEvents->ExtEvents->OnBeforerender :
    function window.OnBeforerender(sender)
{
   Ext.apply(sender, {
			alwaysOnTop: true
   });
}

    Unfortunately, this was not enough the form shows as a regular form. I've also tried to put the full path to AlwaysOnTop.js under ServerModule.CustomFiles: nothing changes.

    What am I missing here?

    Forcing/Constraining form position

    in General

    Posted

    Hi,

    in my application I want the main form to stay in the top-left corner (Top=0 and Left=0). Then, every other form must not overlap it. So, I need some way to detect when any form position change.

    This seemed to me a very basic task, but is not (or I am missing something, which is entirely possible). These are some of the events and properties I tried to manage:

     

    Form->OnClick, Form->MouseDown/Up/Enter... don't help, because they detect only clicks/actions that happen inside the form borders, they do not trigger when the user clicks on the top bar, and therefore he is free to move the form wherever he wants.

     

    Form->DragDrop, Form->EndDock....  they seem to work with components that are inside the form, not with the form itself. Actually, I don't know what their purpose is.

     

    Form->Align=alTop, only works in VCL mode, and does not solve the problem with the other forms that must not overlap the main form.

     

    Form->FormStyle=fsStayOnTop: combined with Align=Top, is a non-optimal solution, but only works in VCL mode.

     

    So, any ideas?

    TUniDateTimePicker, TUniDBDateTimePicker null date - 30/12/1899

    in General

    Posted

    I have an annoying problem, which seems to be quite popular in many Frameworks.

     

    I am writing an application that loads records from a database where, in general, datetime data (timestamps) are nullable. When I display null values using a DateTimePicker i get "30/12/1899" which is an awful default for NULL. All I want is a blank DateTimePicker Field.

     

    So far, the only (not) acceptable workaround I've found is to change the dateformat to "  /  /    " in case of nulls and then reset it to default when the user (or some automatic routine) changes the value to some valid datetime.

     

    Something like:

     

    void __fastcall TFormMain::UniDateTimePicker1Change(TObject *Sender)
{
   if(UniDateTimePicker1->DateTime==0.0){
	  UniDateTimePicker1->DateFormat=L"  /  /    ";
   }else{
	  UniDateTimePicker1->DateFormat=L"dd/MM/yyyy";
   }
}

     

    Following this approach, I have to intercept all the events (not only OnChange) that may trigger from any datetimepicker component that I put in my application. I do not wish to do that, because I am a lazy programmer :|

     

    Any ideas?

    Ext JS OEM License

    Are you allowed to buy an Ext JS OEM license from us?

    Are you using uniGUI in your projects?

     

    Yes, and yes. Nothing changes, for us, if we buy the ExtJS license from you or directly from Sencha.

    I can't donate (my budget is not under my control :S ). But I will be more than happy to pay for Farshad work in the near future (as soon as version 1 is released).

    From the very beginning, it seemed clear to me that UniGUI was going to be a commercial product, and I am 100% OK with that.

    700USD or 350+350 (buying ExtJS separately) makes no difference to me.

    Unfortunately I can't donate, I am not allowed to do that.

    [Design] UniLabel - UniEdit proper alignment

    in Feature Requests

    Posted

    Development Environment:

    Microsoft Windows XP Professional 32bit

    RAD Studio XE2 (c++ builder)

    UniGUI 0.90, 0.91, 0.92, 0.93

     

    In design mode is difficult to properly align a UniLabel with a UniEdit component. Here's why:

     

    1) take a unilabel and a uniedit, drag them in an empty form. Hold down the uniedit with the mouse and try to align it to the label. "Alignment lines" (see picture uniledit1.png) will appear, to help me fit the component in the form. But unfortunately the result is not what i expected: i would like the two components to be aligned accordingly to the text inside them.

     

    2) take the classics: tedit and tlabel. See tedit1.png. See the red line? That is perfect. No need to manually set the top property. :D

    Push notification

    in General

    Posted

    Is there a way to implement some sort of push notification in web mode? I need a form that displays messages sent via UDP/DB pipes/DB alerts... Obviously, there is no way I can predict when these messages will be sent, so periodically (using a Timer) I have to refresh the form.

     

    This is heavy.

     

    Any ideas?

    TUniMemo horizontal scrollbar (not sure if it's a bug..)

    in General

    Posted

    Is there a way to force a TUniMemo to display (in web mode, of course) the horizontal scrollbar instead of automatically add a new line?

     

    Example

     

    New Form. Add a TUniMemo (width <100, ScrollBars BOTH, WordWrap True or False).

     

    Form->OnCreate:

    void __fastcall TMainForm::UniFormCreate(TObject *Sender)
{
  UniMemo1->Lines->Add( u"foobar foobar foobar");
  UniMemo1->Lines->Add( u"foobar foobar foobar");
  UniMemo1->Lines->Add( u"foobar foobar foobar");
  UniMemo1->Lines->Add( u"foobar foobar foobar");
}

     

    When you run the application you'll see that in web mode it only shows the vertical scrollbar and the text is automatically wrapped.

     

    Environment

    Microsoft Windows XP Professional 32bit (also tested on Windows 7 Ultimate 64bit)

    RAD Studio XE2 (c++ builder)

    UniGUI 0.90, 0.91

    Browser Mozilla Firefox 18.0.2, Internet Explorer 8.0.6, Waterfox 18


    Also tested browser: Iceweasel 10.0 (Debian 6, KDE)
