I just added two widgets to a FlexGridSizer using XRCed. This seems to have broken my app and lead to a very hard to understand traceback. Fortunately, I had backed up my last working xrc file and was able to diff them.
Here is what got added to the new, broken xrc:
<object class="wxFlexGridSizer">
<object class="sizeritem">
<object class="wxStaticText">
<label>Plot Name:</label>
</object>
</object>
<object class="sizeritem">
<object class="wxTextCtrl" name="plot_name_ctrl">
<style>wxTE_PROCESS_ENTER</style>
</object>
<option>1</option>
<flag>wxEXPAND</flag>
</object>
<cols>2</cols>
<rows>1</rows>
<growablecols>1</growablecols>
-
<object class="sizeritem"> -
<object class="wxStaticText" name="dummy1"> -
<label>hello</label> -
</object> -
</object> -
<object class="sizeritem"> -
<object class="wxButton" name="duplicate_button"> -
<label>duplicate</label> -
</object> </object> </object> </object> <option>1</option> <flag>wxEXPAND</flag> </object> <object class="sizeritem"> <object class="wxStaticText" name="Filename_label"> <label>Filename</label> </object> <flag>wxTOP|wxLEFT|wxRIGHT</flag> <border>5</border> </object>
Near as I can tell, the two new widgets were added to the xml before the end of the header for the FlexGridSizer.
Here is the traceback:
