Hello,
My
application creates multiple windows which are always created, showed and hid/closed
when some buttons are pressed. These buttons share this style:
<Style
x:Key="MyButtonStyle" TargetType="{x:Type
Button}">
<Setter Property="ClickMode" Value="Press"></Setter>
<Setter
Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type
Button}">
<Grid>
<Rectangle x:Name="RctBtn" Fill="Blue"/>
<TextBlock
Text="{TemplateBinding Content}"></TextBlock>
</Grid>
<ControlTemplate.Triggers>
<Trigger
Property="IsPressed" Value="True">
<Setter
Property="Fill" TargetName="RctBtn" Value="Red"
/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
My code looks like:
public Window1()
{
InitializeComponent();
this.button1.AddHandler(Control.MouseDownEvent,
new MouseButtonEventHandler(openWindow),
true);
this.button2.AddHandler(Control.MouseDownEvent,
new MouseButtonEventHandler(closeWindow),
true);
}
private void openWindow (object sender, RoutedEventArgs
e)
{
/* Here some code */
Window1 w1 = new Window1();
W1.ShowDialog();
}
private void closeWindow (object sender, RoutedEventArgs
e)
{
This.Close();
}
I want to launch this application in
a PC with a touch screen, then I'm using MouseDown event instead of Click
event.
I have realized that when these
buttons are pressed, sometimes, they are not changed to Red. I tried to call
Dispatcher.Invoke with Render priority once the button is pressed but it didn't
solve the problem.
Object.Dispatcher.Invoke(DispatcherPriority.Render,
EmptyDelegate);
Application.Current.Dispatcher.Invoke(DispatcherPriority.Render, EmptyDelegate);
¿Could you help me?
Thank you in advance,
