New button properties are welcome
During the modernization of IDF 9.7 it became clear that 3D buttons could not be used anymore. Windows has gone flat and all the office applications as well. So we needed to address this with some simple properties on the command button widget. The defaults stay untouched even though the new properties make the button more appealing. So we don’t break the look and feel of the existing applications but open the possibilities to a modern user interface.
These new properties make the difference and allow the UNIFACE developer to change the looks of the entire application in a wink. You need to set the button representation to “UNIFACE” is you want to make use of the new properties.
With the new properties we were able to completely mimic the Windows 8 tiles as well as the common flat buttons.
In the following example the “Transparent” property is set while the button is placed on a form with a very colorful image. Not very user friendly, since it looks like a label, but it shows the possibilities.
A button with transparency set to TRUE.
The following table shows a button with an image which is styled in different ways:
New property value
During the modernization of IDF we missed the option to create big buttons with an image big enough to fill up the button. The “imgsize” property has a new value to accommodate the workspace buttons in IDF.
Example the UNIFACE Journey planner
If we start making changes to GUI widgets or the GUI driver, we always look to other applications and try to make the user interface in UNIFACE. For the buttons I took the Android application made by the Dutch national railway company NS. With the new button properties we could mimic the user interface completely. Following picture shows the UNIFACE Journey planner which uses flat buttons.
To make designing the application more easy, I created logical widgets with the necessary properties, so I was able to paint the Journey planner very quickly. Creating the logical widgets was some work but after this you can develop an application following a certain theme. You can paste the following buttons into you usys.ini to get the looks as shown in the sample.
I hope this helps you in creating modern looking UNIFACE applications and modernizing existing applications.
