patch will be made available in case fgfs 0.9.9 is released before plib 0.8.5
right/upper screen edge (analogous to the --geometry spec), assuming
that we never want to draw outside the screen area; for this to work
we need to write the original x/y coords back to overwrite the absolute,
positive values that the layouter stored there
property (e.g. <keynum>49</keynum>). The numbers are the same as in
keyboard.xml. (Could later be replaced/enhanced with <key>Ctrl-a</key>
notation.) This does, of course, only work for widgets with assigned
bindings.
or data blocks) from layouter and dialog creator. This is required for
dynamically generated/modified dialogs. Parts in the XML file can be
hidden and turned on by the C++ code. Other hidden parts can be used
as templates that are multiply used. Hidden datablocks can contain
strings that are used in dialog context, that are easier to translate
or modify in the XML file.
LayoutWidget::setDefaultFont() wants puFont* /and/ pointsize as extra
parameters, when puFont knows its pointsize anyway. Didn't want to change
that yet, though.) Now the HELVETICA_10 font makes actually sense. :-)
- add <vrule>
- allow elements to default to foreground color (black)
- remove redundant if (foo) delete foo;
The rules do currently need a dummy child for the layouter to work correctly,
(<hrule><foo/></hrule>). The goal is to make a simple <hrule/> work.
showDialog() is careful not to create a new FGDialog() if a dialog with the
same name is already open (active). But at this point it is already too late:
newDialog(), which was called shortly before, has already overwritten the
dialog properties. This leads to animated garbage in the best case, and a
segfault in format_callback() in the worst case.
- GUI::newDialog(): Don't you overwrite properties of an active dialog!
- GUI::readDir(): You may do that, but delete the old dialog first!
(necessary for reloading the GUI)
- FGDialog::makeObject(): only set format_callback() with setRenderCallback()
if the property is "live". Otherwise, only call it once at construction
time. This isn't only a performance improvement. Without this the label
was growing until it hit the limit (256).
The previous message wasn't totally correct. Strings are now allowed, too. And
the pattern is now '[ -+#]?\d*(\.\d*)?l?[fs]' and *may* be embedded in a string.
There may only be one %s or %f, though. %% is allowed in the preamble/postamble.
(Yes, %ls is allowed, too, and treated as %s.)
Also, "end" is superfluous now.
Printing floats in dialogs with 8 digits after the comma is inappropriate
for most cases.
- implement a "format" property for "text" gui elements (a.k.a. pui label).
Number formats are set by strtod/snprintf, while formats on non-numbers
are replaced by "%s". Practical example in the upcoming material.nas update.
Valid formats regex: '%[ -]?\d*(\.\d*)?l?f' (IOW: the format must begin
with '%' and end with 'f').
# Nasal:
number = dialog.addChild("text");
number.set("label", "3.1415926");
number.set("format", "%.3f");
The dialog handling has been written at a time when only one dialog was
shown at the same time, and dialogs were shallow -- with only children, but
no grand-children. This makes finding a draggable spot on modern, dialogs
with nested objects quite a challenge. The patches fixes this, and other things:
- check full object tree on button press, not only the outmost layer;
and don't give up just because we are in *something* (which could well be
something harmless, like a group); only ignore a few, sensible objects
(we don't want to drag after a click on a button or into an input field)
- don't lose dialogs as easily when dragging too fast (it does still happen
if one manages to enter an editable field while dragging, but this is
a plib problem and I don't feel like fixing that now :-)
- don't "live"-update input fields while they are in edit mode
- remove some "if (foo) delete foo;" redundancy
I have made the
'Select Airport from List' option in FlightGear work
(I think) properly. I have some concerns about the
solution, which could be broken by changes to plib (if
they re-use the value I have assigned to
PUCLASS_LIST), but for the moment it seems to work OK.
Erik Hofman:
A request has been sent to John Fay to include the puList
code in the puAux subdirectory of plib so expect some
changes for future version of FlightGear.
I'm attaching a small change to Andy's dialog.cxx that I needed
to make so that it enables XML/Nasal-dialogs to also contain
puLargeInput boxes.
The text will be retrieved/buffered from/within a specified
property tree, like:
<textbox>
<x>100</x>
<y>100</y>
<width>200</width>
<height>100</height>
<property>/gui/path-to-text-node/contents</property>
<slider>15</slider>
<editable>true</editable>
</textbox>
little larger.
The text widget can now be meaningfully associated with a property; in
PUI, it's "value" isn't the same thing as its label, but we can hack
things to treat them symmetrically.
Commit an experimental "live" property that can be set on widgets to
cause them to update their values every frame. This works great for
text widgets, as above. Note that this synchronization is input-only:
no support is provided (or needed -- the GUI only changes when the
user does something) for writing those properties out every frame.
for a while, it turned out to be pretty easy to implement. Also, the
property picker is now non-modal, I presume the modality wasn't an
intentional feature.
TITLE: Using delete [] versus delete
The extra "[]" warns the compiler that there is a whole array of objects here so that P's destructor must be called on each element of the array rather than just on P itself (which would be equivalent to the first element only).
Fix memory leaks (PUI doesn't make copies of lists, so we have to make
our own copies and keep pointers to them).
Adjust for new method names in NewGUI.
Move the GUIInfo struct into the cxx file so that it's not part of the
public interface.
