Problems: |
| 31 |
|
| 32 |
1. The wxTextCtrl should fit to the right side of the horizontal |
| 33 |
box/sizer. It doesn't. I only found the sizer.Add() method to |
| 34 |
be able to take proportions but no way to tell the object to |
| 35 |
fill all remaining space. |
| 36 |
|
| 37 |
2. The framed box "Layers" needs to be scrollable if there are |
| 38 |
more than 12 items, since the dialog would probably not fit on |
| 39 |
people's screen anymore. |
| 40 |
|
| 41 |
Todo: This can be solved (in C it was possible at least), |
| 42 |
probably with wxScrolledWindow |
| 43 |
|
| 44 |
3. The button hbox is not aligned to the right side which should |
| 45 |
be. For some reason wxALIGN_RIGHT does not have any effect. |
| 46 |
Maybe I just misunderstood the documentation? |
