Program nearly always starts maximized.

[alantcote]

The program nearly always starts up maximized.

Expected Behavior

It should "remember" the window geometry for the next use, or choose one which isn't so greedy for screen real-estate.

Current Behavior

The program nearly always starts up maximized.

Steps to Reproduce

The only thing I've had to do to reproduce the problem is to start up the program.

Your Environment

I nearly always start SceneBuilder from within the Eclipse IDE, on MS Windows 11.

Hi @alantcote, I am analyzing the issue and learned, that Scene Builder indeed always starts maximized by default. An exception is MacOS, there Scene Builder does not start maximized.

How it works:

The windows is positioned in com.oracle.javafx.scenebuilder.app.DocumentWindowController within the openWindow() method. Here a conditional call to getStage().setMaximized(true) is placed when the platform is not MacOS. There is a corresponding closeWindow() method.

Both places seem to be suitable to implement a point so memorize and load the actual window position. This could be handled by com.oracle.javafx.scenebuilder.app.preferences.PreferencesController which offers the method PreferencesRecordDocument getRecordDocument(final DocumentWindowController dwc). The PreferencesRecordDocument stores all view related settings such as stage height, visibility of elements and so on. So

The solution approach could be:

• add fields for window size and window position to PreferencesRecordDocument
• update DocumentWindowController.openWindow() so that stage size is set according to values in PreferencesRecordDocument (this must include a check that the window size and position suits the available screen space and an adjustment if screen space is not sufficient)
• update DocumentWindowController.openWindow() so that last stage size and position is saved to PreferencesRecordDocument
• the maximized view for the first start shall remain as default as currently configured
• Add an option to PreferencesWindowController asking the use if Scene Builder shall start maximized (by default) using a checkbox

Questions:

@johanvos, @abhinayagarwal, @AlmasB:

• If Scene Builder would memorize window sizes and positions, shall this be the default behavior then or is it desirable to switch this off using Scene Builder preferences dialog?

[alantcote]

Your proposal sounds good to me.

[abhinayagarwal]

My personal preference would be to have an option to toggle this feature from the preferences dialog.

[Oliver-Loeffler]

An option preferences dialog seems like a good idea. It provides a choice to the user.

[alantcote]

Potentially useful if you implement the proposal would be my Preferences editor. It's a bit rough; if you know of a better tool for the purpose, please elucidate.

[paul-court]

Would it be simpler (from both code and UX) to just remember the maximised state along with the window geometry instead of having to go and hunt down a preference option?
