PS: In this version Ext JS version has upgraded to 3.4.0, so you may need to re-adjust ServerModule->ExtRoot parameter. You don’t need to change anything if it is already set to ‘ext-x.y.z\’, as it will automatically point to new ext-3.4.0 folder.
Also don’t forget to deploy ext-3.4.0 folder to your servers.

One of the exciting new features in version 0.86 is ability to write client side JavaScript event handlers from within Delphi IDE. Each uniGUI control is attached to an Ext JS control. In some cases there are more than one Ext JS controls for a uniGUI control. For example a TUniForm is a combination of an ext.Window and an ext.form.FormPanel.
Below image shows uniGUI event editor. All available events are listed in right panel. You can create an empty event handler by double clicking on event.
Now you can easily write a proper handler for mousemove event. In below example mouse coordinates are shown inside a TUniEdit control.
function form.Onmousemove(sender, x, y)
{
MainForm.UniEdit1.setValue(x + ':' + y);
}
As you can see, you can easily refer to screen objects using their Delphi names. In above code, UniEdit1 is an Ext.form.TextField object. You can refer to Ext JS API docs for a list of available functions for all Ext JS objects.
On client side, Forms and Frames are global JS objects. Individual Controls are defined as sub-properties of Forms and Frames.
For controls residing inside a Form you must access them as child objects of that Form:
MainForm.UniButton1.setText('Caption');
UniForm2.UniButton3.setText('Caption');
For controls residing inside a Frame you must access them as child objects of that Frame:
UniFrame1.UniEdit1.setValue('Text');
Please note that JavaScript is a case-sensitive language so object JS names should be same as those declared in Delphi:
Delphi name: UniEdit1
Correct JS name: UniEdit1
Incorrect JS names: uniEdit1 Uniedit1
Another advanced feature is ability to call server side event handlers from JS code. It enables developers to write fully customized server side Ajax event handlers
Example:
In a TUniButton control add below code to client side OnClick event.
function OnClick(sender, e)
{
ajaxRequest(sender, 'MyEvent', [ 'param0=A', 'param1=B' ]);
}
In Object Inspector add a Delphi event handler for UniButton OnAjaxEvent event:
procedure TMainForm.UniButton1AjaxEvent(Sender: TComponent; EventName: string;
Params: TStrings);
begin
if EventName='MyEvent' then
begin
UniButton1.Caption:=Params.Values['param0'] + Params.Values['param1'];
end;
end;
All these features enable developers to handle some of the events on client side and only call server side handlers when it is needed. This will highly improve user experience and overall application performance. One good example is our Google Maps Demo which is a balanced mixture of client side scripts and server event handlers.
After a long intermission a new version of uniGUI framework is available for public download. Version 0.86 can be considered as a new milestone for uniGUI framwork.
It introduces many new features and enhancements:
- Completely renewed and redesigned framework core.
- Extended server side event handling for Click and mouse events.
- HTTP Compression
- Advanced client side event scripting.
- Interaction between client side Ext JS components and JavaScript code.
- Advanced IDE editor to add and edit JavaScript handlers for Ext JS controls
- Directly fire Ajax requests from JS code.
- Ability to access Ext JS controls from JS code using their Delphi names.
- Ability to monitor Ajax calls on client side.
- Ability to send JavaScript code or custom strings as response to an Ajax request.
- Server side mouse and click event handlers added for additional uniGUI controls.
- Extended client side mouse and click event handling support for Ext JS controls.
- New Calendar Panel component
- New demos
- Many bug fixes, other improvements and other new features.
In some areas version 0.86 breaks compatibility with previous versions, so if you have developed uniGUI projects with version 0.84.x or an earlier version please read carefully the Migration to version 0.86 article before you open your projects with version 0.86.

As we discussed earlier versions 0.85 and 0.86 will be new milestones for uniGUI library. They will introduce new framework core which brings lots of architectural changes and improvements.
Here is a brief list of these changes:
- All controls will be descendant of a common root opposed to previous releases where each Control had a different ancestor.
- Only implemented properties and events are published. This will avoid confusion in previous versions where lots of public and published features in VCL mode were not implemented in Web mode.
- Class types no longer change among Web and VCL. Now TUniButton is always a TUniButton regardless of the displayed mode.
- In event handlers Sender parameter will always contain correct class type.
- As a result of above changes you can safely use as and is operators.
- Advanced client side event scripting.
- Extended Server side event handling for click and mouse events.
Other benefits of this new core will become manifest as framework continues to grow. For example, without new core integration of client side scripting would be very difficult.
Since it contains some huge changes, incompatibility with older versions is inevitable. i.e. it will not be as easy as opening your projects and simply recompiling it. In some areas it breaks compatibility and you must go through a procedure to make your existing projects compatible with 0.86.0.
Here is the receipt. Please follow these steps exactly as described in below order.
- Completely uninstall any previous version of uniGUI and remove uniGUI design time libraries from Delphi IDE.
- Download and install the latest build for version 0.86.0.
- As always build all packages and Install the design time packages.
- Make a full backup of your existing project which you want to convert.
- Before you open the project in Delphi IDE do the following changes.
- Locate Forms which contain TUniPageControl component.
- Open the associated DFM file in a Text Editor and replace all TTabSheet instances with TUniTabSheet.
- Save the DFM file and repeat this for all Forms containing TUniPageControl control.
- In order to simplify next steps you can delete the DSK (Desktop) file of the related project.
- Open the project in the IDE.
- Open ServerModule.pas.
- IDE will nag you for some properties that no longer exist. Ignore them and save the ServerModule.pas.
- For all Forms and Frames in project open them one by one. Again IDE will warn you about several properties that aren’t published anymore. Press Ignore all and save the Form.
- When you try to save modified Form, IDE may complain about some components that have incorrect class types. IDE will prompt you to correct the problem. Answer Yes to all prompts and save the Form.
- Repeat above steps for all Forms and Frames.
- Now try building the project.
- Compiler will generate errors for units X,Y, Z… that do not exist anymore. (e.g. UniControls, UniExtControls, …etc.) Remove these units from Uses list and save the Form.
- For some Forms compiler may generate error for some “Unknown class type“. Add UniGUIAbstractClasses to Uses list of Form and recompile the project.
Now you have successfully converted your project to version 0.85 and you can run and test it in a web browser. Hopefully all converted projects should run as expected in both VCL and Web mode. If not try to localize the problem or look at the browser JS error logs.
