Hello everyone,
I want to find way to remove / breaking limit of attribute Spinmin and Spinmax
of iup control - Text with Spin attribute.
Although user could input (directly, not by spin button) or paste any value, it
will affect control's Value attribute. But the control's Spinvalue attribute is
limited at Spinmin or Spinmax, which would be used by spin.
Means you paste -100, it turns to 0 on click spin-down, and 1 on click spin-up,
Their default value is Spinmin - 0 and Spinmax - 100..
Currently, I use valuechanged_cb to change Spinmin, Spinmax to follow Value.
Like:
i.text{spin = 'YES',
valuechanged_cb =
function(self)
local value = self.value
local spin_increment = 20
if(self.spinmin >= value)then
self.spinmin = value - spin_increment
elseif(self.spinmax <= value)then
self.spinmin = value + spin_increment
end
self.spinvalue = value
end,
} could use 'tonumber' first to check value, if it is a number
then it could be used for spinvalue.
'spin_increment ' should bigger than 20, for "In Windows, the increment
is multiplied by 5 after 2 seconds and multiplied by 20 after 5 seconds of a
spin button pressed."
So, any ideas?------------------------------------------------------------------------------
