Hi Jamal: So much depends on what the application will be used for and exactly
what options will be made available.
If the number of colors and sub-colors are not too many then all the colors
could be grouped in a list or dropdown list and there is just one color for
each selection instead of one color and then another sub-color.
Blue:
Blue-Light
Blue-Navy
Blue-Sky
Red:Red-Dark
Red-Light
etc...
Then first letter navigation gets you to the base color and a sighted user is
set and a blind user can just arrow key or mouse down the list of sub-colors to
pick one. That eliminates the complexity of having a TreeView or a second color
ListBox.
I dont recall if he said he is going to allow for a cloth selection or not so
couldnt do a solid layout.
But if only an item and a color then only 2 dropdown lists or ListBoxes are
required, if cloth is included then 3.
A Review TextBox, Label or even a PopUp with the Review Window is the only
other control other than the buttons.
This is pretty straight forward to implement in vb.net and easy to navigate
for both sighted users, mouse users, and sighted screen reader users, first
letter navigation - hit the letter b to go to the Blue group then just cursor
or mouse down and click a sub color.
This is one layout I would consider in place of a sub-color control.
Also, he didnt mention but if a production application it is quite likely
there wont be the same colors available for socks, shirts and pants so the
lists, the Color List at least, would have to be dynamic
Then in the SelectedIndexChanged event the color box would be populated with
the appropriate colors for each item as it is selected in the ClothingItem List.
If Cloth is another selection, again I dont know, when a different
ClothingItem is selected, or different cloth is selected, the appropriate
values need to be updated in the child boxes. For a ClothingItem the cloth and
the colors need to be set and a default cloth and default color for the default
cloth set as the selected index of those boxes for the selected ClothingItem.
Two things of note...
1) This might not be the best layout using VBS since I am not familiar with
the events of the VBS controls and Dialogs.
2) If there is going to be a database or xml file or some other way to
dynamically load contents into the boxes I would design that first and see what
technicals are available for loading the available cloths for a Selected
ClothingItem and what colors are available for each type of cloth.
Then populate the file, db or whatever with a few colors like the ones
mentioned above for testing my UI which I would then layout and test with the
limited inputs.
