Hi,
I would like to have a widget_draw (or widget_window) within a widget_base with stuff on the top, left, right and bottom of the draw widget. If I change the size of the base with the mouse, I would like the draw widget to expand accordingly.
I found a way to do this, by keeping track of the size of the widgets (base and draw). However, I'm wondering if there is a cleaner way to do this.
Here is an example code:
pro testWidgetRescale_event, event
widget_control, event.top, get_uvalue=struct
newBaseGeometry = widget_info((*struct).wb, /geometry)
baseDiff = [newBaseGeometry.xsize-(*struct).baseGeometry.xsize, newBaseGeometry.ysize-(*struct).baseGeometry.ysize]
widget_control, (*struct).wd, xsize = (*struct).drawGeometry.xsize+baseDiff[0], ysize = (*struct).drawGeometry.ysize+baseDiff[1]
(*struct).drawGeometry = widget_info((*struct).wd, /geometry)
(*struct).BaseGeometry = newBaseGeometry
end
pro testWidgetRescale
wb = widget_base(/tlb_size_events, /tlb_move_events, column=3, /BASE_ALIGN_CENTER, /ALIGN_CENTER)
void = widget_label(wb, value=' some stuff here', /align_center)
row2 = widget_base(wb, /column)
void = widget_label(row2, value=' some stuff here')
wd = widget_draw(row2, xsize=500,ysize=500)
void = widget_label(row2, value=' some stuff here')
void = widget_label(wb, value=' some stuff here', /align_center)
widget_control, wb, /realize
baseGeometry = widget_info(wb, /geometry)
drawGeometry = widget_info(wd, /geometry)
widget_control, wb, set_uvalue=ptr_new({wb:wb, wd:wd, baseGeometry:baseGeometry, drawGeometry:drawGeometry})
xmanager, 'testWidgetRescale', wb, event_handler = 'testWidgetRescale_event' , /no_block
end
thanks,
Helder

thanks David. I was hoping in some hidden "dynamic_resize_magic" keyword...
Cheers,

I am working on style sheets for widgets in FL. Here is an example:
pro test
base=widget_base(xs=200, ys=100)
text=widget_text(base, value="Hello world!", xoff=50, yoff=30, xs=100, ys=50, $
style_sheet="background-color: green; color: yellow")
widget_control, /realize, base
xmanager
end
It produces this widget: http://fl.t15.org/hello.png
But is is far from complete :-(
regards,
Lajos
