Control Panel

 General
 

The wiris control panel (figure 2) appears pressing the icon that is in the system tray (figure 1), in the toolbar of the calculator or using the shortcut in the start menu.

Figure 2. Control panel of wiris local desktop, opened with the General page.

Through the control panel is possible to know the state of the kernels and change the configuration of the server. It is composed of two pages that can be toggled, clicking the General and Configuration tabs. The Ok button activates and saves the changes of the configuration. The button Cancel ignores and does not save the changes of the configuration. The button About wiris, returns generic information about what is and who developed wiris local desktop.



 General
The General page returns a description of the state of the kernels. It also permits perform the actions: close the server, restart all kernels and open the calculator or the manual.













The panels Activity and State show information about how many kernels are calculating and the number of opened kernel and the calculations performed since the wiris server started, respectively. The meaning of the number of opened kernels is slightly different when the operating system is Windows 98/Me or Windows NT/2000/XP; in these last operating systems, whenever a calculation is performed, there are at least 2 kernels because one of them is the model (or seed) kernel, from which the remaining kernels are cloned.

Let us see the actions performed by the buttons:

  • Restart: closes all kernels and opens only the initial kernel. If a lot of simultaneous calculations have been executed, this button closes all kernels. It is also useful to stop a very long time consuming calculation.
  • Close all: stops the server. After stopping the server, it is not possible to calculate with wiris. To activate the server again, it suffices to execute the wiris server.
  • Calculator: opens a web page with the calculator.
  • Manual: opens a web page with the manual.

The text that corresponds to Configuration, inside the State panel, shows whether the calculator that is been using is the local or the Internet one. In the configuration page is possible to activate o deactivate the use of the local version; but this change will not be effective until there is no other opened calculator or browser that had used the calculator at any moment. More precisely, to be sure that the change has effect, the best is close all browsers and, maybe, restart the computer (Windows 98/ME).















The behaviour can be changed checking the following options.

  • Open Internet pages using wiris local desktop Using wiris local desktop is by default selected. In this case, all wiris calculators related to wiris local desktop will be opened and will calculate with wiris local desktop; to sum up, it will be possible to calculate being off-line. Otherwise, it will use the Internet calculator sited in the portal wiris local desktop; even if the calculator is opened through the shortcut in the desktop (start/programs).
  • Initialize when Windows does Is selected by default. If it is selected, whenever a Windows session starts, the wiris server will also start. It is recommended to activate this option, otherwise, when a page that contains wiris is visited after restarting Windows, it will not possible to calculate until the server is started manually.
  • Write log files. Is selected by default. If selected (you should restart the server), information files will be created in the log folder inside the installation folder of wiris local desktop.
  • Delay first kernel load Is selected by default. When it is selected, the fist time that a calculation is performed, after starting or restarting the server, wiris should wait until an OmegaKernel is loaded. Otherwise, the first calculation is done faster without waiting for the kernel load; this implies that there is always an opened kernel.
  • Maximum number of kernels By default are 10. When there is more than one browser with the calculator, it is possible to calculate with all of them. If two calculations are simultaneous, a new OmegaKernel will be opened; the number of kernels can be limited using this property. When the top of kernels is reached and all of them are calculating, the new calculations are delayed until a kernel is free.
  • Memory limit By default are 20 MB. It is the maximum amount of memory, in megabytes, that a single OmegaKernel can use. This value is an approximation and it is less than the real memory used.
  • Maximum calculation timeout By default are 10 seconds (10000 ms). It is the maximum time that a kernel spends for a single calculation. The calculations that long more that this time are cancelled.
  • Language It is possible to change the language. The chosen languages apply to the control panel, the new opened calculators and manual.

Note that the configuration change has no effect until the button Ok is pressed or when changing the page to General. In this two situations and if the change can not be done immediately, a message box will say that all browsers must be closed, and, if the operating system is Windows 98, it will be necessary to restart the computer manually. To know whether the changes have been activated properly, it suffices to test the value shown next to the label Configuration of the State panel in the General page of the control panel of wiris local desktop.
