B4A Library Dialogs library

This library contains several modal, that is blocking, dialogs by which the user can enter data. Presently they are an InputDialog for numbers and text, a TimeDialog for times and and a DateDialog for dates.

Note that modal dialogs can close unexpectedly and not return to your code if the Activity needs to close, most likely because the user rotated the device. There is a brief discussion of this in the overall library help in the xml. This can also occur with the Basic4android modal dialogs InputList, InputMultiList, Msgbox and Msgbox2 whose modal mechanism is used by the dialogs in this library.

Andrew,
I have Dialogs library 2.30.
When I scroll the FileDialog, the scroll color becomes grey/transparent and becomes normal after scrolling.
I believe there was a fix for this around 1.7
I am not sure if anyone else is seeing this problem?

 

[agraham]

I overlooked exposing the ScrollingBackgroundColor like ListView does. I'll fix it soon.

 

[vangogh]

numeric keypad?

I have dialog lib v2.2 so sorry if I miss the new feature

I miss a "numeric keypad", like the one used to compose a telephone number...
numbers 0-9, dot, delete, cancel and OK...
the numeric view I know (I have in my 2.2 lib) uses the "+" and "-" to compose a number...

Am I missing something, or a "numeric pad" is not already present?

thank you

Try an InputDialog with InputType set to INPUT_TYPE_DECIMAL_NUMBERS.

 

[JesseW]

Or INPUT_TYPE_PHONE

In version 2.5 now posted FileDialog has grown a ScrollingBackgroundColor property like a ListView.

Also included is a third colour dialog I was playing with that lets you specify a colour by its Hue, Saturation and Value which might sometimes make selecting the right colour easier. I hadn't really intended to publish this but as it was in the library source I let it go through rather than deliberately removing it.

That was fast. Thanks

I am not sure if this is a bug (but this was not a problem in 2.30)
If you do not set the FileFilter property before you invoke .Show, the dialog crashes the app.

 

[thedesolatesoul]

Another question about the FileDialog.
Is it possible to add an icon for the Folders, so they can visually be more easily distinguished from the filers?
Thanks

 

[agraham]

If you do not set the FileFilter property before you invoke .Show, the dialog crashes the app.

Oops! It's a bug introduced in version 2.4 when I allowed multiple filters to be defined in a comma separated string. For now just initialise FileFilter with an empty string if you don't want filtering.

Is it possible to add an icon for the Folders

I'm not really a UI person so to save thinking about it I used SingleLineLayout from the Basic4android ListView for the file and folder entries so the answer is no for now.

[thedesolatesoul]

Can the Filedialog act as a FolderDialog i.e. just to select a folder rather than a file?
I need the user to select a location, but not a file.

EDIT: Okay, I got around this by using a custom dialog and it was very easy
but i have a question...when the dialog opens up, the user doesnt really know which directory he is starting from, should we add the current path to the title or something like that?

 

[agraham]

Version 2.6 now posted fixes the bug in introduced 2.5 that crashed FileDialog if a FileFilter was not explicitly specified.

FileDialog now has a ShowOnlyFolders property that if set True will only display the existing folder names and will allow the user to enter a new name for a new folder if required.

Thanks!

I have a listview added to a panel inside the customdialog2. I tried to get the Listview_ItemClick to find out the user selected item but it didn't work. Is it not possible to trap events of a view inside customdialog?

 

[agraham]

Yes, the Custom demos do it for a button.

Make sure your not using a msgbox inside the listview event. They don't show until the custom dialog has completed.

I didn't. Have you tried Listview on CustomDialog2 before?
